Proper cleaning of farm facilities is the critical first step in any successful biosecurity program. Before applying any disinfectants or biocides, all organic matter — including manure, litter, feed residues, blood, and stubborn biological biofilm — must be thoroughly and systematically removed. In Bangladesh's rapidly expanding poultry, dairy, and aquaculture industries, inadequate cleaning protocols remain one of the primary causes of recurring disease outbreaks, leading to devastating production losses and decreased profitability.

Farm managers often make the costly mistake of relying solely on disinfection, bypassing the essential detergent cleaning phase. However, you simply cannot disinfect dirt. Organic loads neutralize even the strongest disinfectants. To combat the unique challenges of high humidity, dense farming models, and challenging environmental factors in South Asia, robust agro cleaning Ingredients in Bangladesh are required.

Bangladesh's agricultural sector — particularly its poultry, dairy, pig, and aquaculture industries — operates in a tropical climate that presents year-round biosecurity challenges. High humidity, temperatures exceeding 35°C, and intensive animal housing conditions create ideal environments for pathogenic bacteria, viruses, and parasites to thrive and spread. Disease outbreaks in poultry farms, fish ponds, and dairy facilities cost Bangladesh's agricultural sector billions of taka in production losses, medication costs, and mortality every year.

The single most important — yet most frequently underestimated — step in preventing these disease outbreaks is thorough, effective cleaning before disinfection. Without proper cleaning, disinfectants cannot reach bacterial biofilms and viral particles protected by layers of organic matter. Contaminated surfaces, manure residues, feed spillage, and biofilm dramatically reduce the efficacy of even the most powerful disinfectants by up to 90%.

ZHM Group, Bangladesh's trusted industrial ingredient supplier with over 20 years of experience, supplies four specialised agro cleaning ingredients — PL56, EWA® FIX, POLYCLEAN, and EWA® FOAM ULTRA — sourced from globally certified manufacturers and used by farms across Bangladesh for effective biosecurity cleaning programs. All products are supplied with full Technical Data Sheets (TDS), Safety Data Sheets (SDS), and application guidance from our technical team. 

What are Agro Cleaning Ingredients?

Agro cleaning ingredients are specialised chemical formulations engineered specifically for the harsh, high-load environments of commercial agriculture and livestock farming. Unlike standard household or commercial janitorial cleaners, agro cleaning products must tackle extraordinary levels of complex organic matter—including concentrated animal feces, uric acid, heavy fats, blood, feather dust, and robust bacterial biofilms.

At their core, the most effective agro cleaning Ingredients in Bangladesh consist of a synergistic combination of high-grade alkaline builders, powerful surfactants (surface-active agents), and advanced chelating agents.

• Alkaline Builders: Chemicals such as sodium hydroxide or potassium hydroxide raise the pH of the cleaning solution. This high alkalinity is necessary to trigger saponification, a chemical reaction that literally transforms stubborn, water-insoluble animal fats and greases into water-soluble soaps that can be easily rinsed away.
• Surfactants: Water alone has a high surface tension, meaning it tends to bead up rather than soak in. Surfactants drastically reduce this surface tension, allowing the chemical mixture to penetrate deep into the microscopic pores of concrete floors, wooden structures, and plastic slats where pathogens actively hide. They also help emulsify oils, holding them in suspension so they do not redeposit onto the surface during rinsing.
• Chelating Agents (Water Softeners): In many agricultural regions of Bangladesh, borehole water is "hard," containing high levels of dissolved calcium and magnesium. Chelating agents bind to these minerals, preventing them from neutralizing the surfactants and stopping the formation of white mineral scale on expensive automated farm equipment.

By combining these highly active ingredients, heavy-duty farm detergents strip away the protective organic layers that harbor disease, effectively resetting the microbiological environment and preparing the surface for successful terminal disinfection.

Why Farm Cleaning Is the Foundation of Biosecurity

When discussing biosecurity on commercial farms, the conversation frequently gravitates towards advanced disinfectants, vaccines, and secure perimeters. Yet, the absolute foundation of keeping a farm pathogen-free is physical and chemical cleaning. Understanding why you need specialized farm cleaning Ingredients in Bangladesh requires a deep dive into the microscopic environment of a livestock facility.

Many Bangladesh farm managers focus their biosecurity investment on disinfectants — assuming that spraying a powerful disinfectant over a dirty surface will eliminate pathogens. This is a costly and dangerous misconception.

The Threat of Organic Matter and Biofilms

During a typical production cycle—whether it is a 35-day broiler flock or a long-term dairy operation—the housing facility accumulates massive amounts of organic waste. This waste consists of fecal matter, unconsumed feed, feather dust, animal fats, and respiratory secretions.

If this organic matrix is washed only with plain water, two things happen:

1. Fat and Protein Adhesion: Water alone cannot break down lipids (fats) and proteins. They remain adhered to concrete floors, feeding lines, and plastic slats.
2. Biofilm Formation: Bacteria such as Salmonella, E. coli, and Campylobacter secrete a slimy extracellular polymeric substance (EPS) that anchors them to surfaces. This is known as a biofilm. Biofilms act like a microscopic fortress, shielding the bacteria from heat, dryness, and chemical disinfectants.

The Organic Matter Problem

Pathogenic microorganisms — including Avian Influenza virus, Newcastle Disease Virus, Marek's Disease virus, Salmonella, E. coli, Clostridium, and Campylobacter — do not exist in isolation on farm surfaces. They are embedded within layers of organic matter: manure, feed residues, feather dander, dead skin cells, and biofilm (the protective slime layer secreted by bacteria colonies on surfaces).

This organic matter has two critical protective effects:

1. Physical barrier: Organic matter physically shields microbial cells from disinfectant chemical contact
2. Chemical neutralisation: Organic matter chemically inactivates many disinfectants, dramatically reducing their effective concentration

Research consistently shows that surfaces covered with even 1mm of organic matter can reduce disinfectant efficacy by 60–90% — meaning a farm manager applying disinfectant to a dirty surface is wasting money while maintaining dangerous pathogen levels.

The Chemical Reality: Neutralization of Disinfectants

Disinfectants (like glutaraldehyde, quaternary ammonium compounds, or peracetic acid) work by attacking the cell walls of pathogens. However, if organic dirt covers these pathogens, the disinfectant reacts chemically with the dirt instead of the bacteria. The active biocide is entirely consumed and neutralized by the manure, leaving the underlying bacteria completely unharmed.

By applying a high-quality alkaline detergent prior to disinfection, you alter the chemistry of the surface. Specialized detergents contain specific surfactants (surface-active agents) that reduce the surface tension of water, allowing it to penetrate microscopic cracks in concrete and wood. Furthermore, alkaline cleaners carry out saponification—a chemical reaction that turns animal fats into water-soluble soaps, making them incredibly easy to rinse away.

The Clean-Disinfect-Dry Protocol

Effective farm biosecurity follows a strict sequence:

1. Remove and dispose — dry removal of all litter, manure, and feed residues
2. Pre-soak — apply cleaning product to loosen dried-on organic matter and biofilm
3. Scrub and wash — mechanical cleaning with brushes, foam, or high-pressure water
4. Rinse thoroughly — remove all cleaning product and loosened organic matter
5. Dry — allow surfaces to dry completely (wet surfaces reduce disinfectant contact time)
6. Disinfect — apply appropriate disinfectant to the now clean, dry surface
7. Dry again — allow disinfectant to work and surfaces to dry before restocking

Economic Impact on Bangladeshi Farms

In Bangladesh, where the poultry sector contributes significantly to the national GDP, outbreaks of Avian Influenza (Bird Flu), Newcastle Disease, and Infectious Bursal Disease (Gumboro) can wipe out entire investments. Using dedicated poultry house cleaner BD solutions ensures that the viral load is mechanically and chemically stripped from the environment before new day-old chicks (DOCs) arrive. Investing in premium cleaning chemistry drastically reduces mortality rates, lowers veterinary medicine costs, and improves the Feed Conversion Ratio (FCR) by ensuring birds do not waste energy fighting off background infections.

ZHM Group supplies all four cleaning products required for steps 2–4, covering different farm facility types and soiling levels. Understanding which product to use in which situation is the key to cost-effective, effective farm cleaning.

Agro Cleaning Ingredients Full List

PL56 — Multi-Purpose Alkaline Farm Cleaner

PL56 is a concentrated alkaline detergent formulated for general-purpose cleaning of farm buildings, equipment, vehicles, and ancillary facilities. It is the everyday workhorse cleaning ingredient for farms that need a reliable, cost-effective, broad-spectrum cleaner for routine cleaning tasks.

When farm managers seek a versatile, highly effective, and reliable detergent for daily or turnaround cleaning, PL56 is the industry standard. As a multi-purpose alkaline cleaner, PL56 is formulated to cut through standard agricultural soils quickly and efficiently without causing damage to sensitive farm equipment.

How PL56 Works

PL56 is formulated with a blend of alkaline builders, anionic surfactants, and sequestering agents. Alkaline cleaners are particularly effective against the types of soiling common in farm environments:

• Manure and faecal matter — organic protein and fat-based soiling
• Feed residues — starch, fat, and protein deposits from feed spills
• Grease and mineral deposits — on equipment, vehicles, and water pipelines
• Biofilm — the protective bacterial layer that forms on all farm surfaces over time

The high pH (alkaline) environment breaks down the protein and fat structure of organic soiling, while the surfactants reduce surface tension — allowing cleaning solution to penetrate between the surface and the soiling layer. 

Active Ingredients and Chemical Profile

PL56 is formulated with a precise blend of alkaline builders, non-ionic and anionic surfactants, and highly effective chelating agents (water softeners).

• pH Level: PL56 typically operates at a high alkaline pH (around 11.5 to 12.5 in concentrate), which is necessary to break down acidic organic wastes like poultry manure and uric acid.
• Surfactant Package: The specialized surfactants in PL56 aggressively lower the surface tension of the washing water. This allows the cleaning solution to seep deep into the porous concrete floors commonly found in Bangladeshi poultry sheds.
• Chelating Agents: Hard water is a common issue across many districts in Bangladesh. PL56 contains chelants that bind to calcium and magnesium ions in hard water, preventing them from interfering with the cleaning process and stopping the formation of white mineral scale on equipment.

Dilution Rates and Application Methods

One of the primary benefits of using PL56 farm cleaner Bangladesh is its economical dilution rate.

• General Cleaning: For standard soiling between flocks, PL56 is typically diluted at 1% to 2% (10 to 20 ml per litre of water).
• Heavy Soiling: For heavily caked manure or extended production cycles, the concentration can be increased to 3% to 4%.

The application is straightforward. PL56 can be applied using standard knapsack sprayers, power washers, or automated dosing systems. The solution should be sprayed onto all surfaces until thoroughly wet and allowed a contact (dwell) time of 15 to 20 minutes. This gives the chemical time to penetrate and lift the dirt. Crucially, the solution must not be allowed to dry on the surface before high-pressure rinsing.

Compatible Surfaces and Applications

PL56 is exceptionally versatile. It is safe to use on concrete, stainless steel, heavy-duty plastics (like feeder pans and drinker lines), and glazed tiles.

• Poultry Farms: Cleaning floors, lower walls, extractor fans, and feeding equipment.
• Dairy Farms: Washing down milking parlor floors,milking equipment, holding pens, and calf hutches.
• Transport/Farm Vehicles: An excellent choice for washing the exterior and interior of livestock transport trucks, ensuring pathogens are not carried between different farm sites.
• Pig farm cleaning — pig house structures, farrowing crates, equipment
• Aquaculture facility — tank walls, pipework, feeding equipment
• Storage areas — feed warehouses, grain stores, equipment sheds
• Water tanks and pipelines — removing scale and organic deposits

EWA® FIX — Heavy-Duty Alkaline Foam Cleaner

EWA® FIX is a professional-strength, high-foam alkaline cleaner specifically engineered for heavily soiled poultry houses, pig facilities, and other farm buildings where ordinary cleaners fail to deliver the degreasing and soil-penetrating performance required. It is the product of choice for terminal cleaning — the deep clean performed at the end of a production cycle before full disinfection.

For environments dealing with severe, built-up organic matter, standard liquid detergents may run off vertical surfaces too quickly to be effective. This is where EWA® FIX—a highly specialized, heavy-duty alkaline foam cleaner—becomes an indispensable tool for farm hygiene.

The Foam Cling Technology Advantage

The defining feature of EWA® FIX is its foam cling technology. Standard liquid cleaners applied by spray or pressure washer run off vertical surfaces (walls, pillars, cage structures) before they can penetrate and loosen dried-on organic matter. EWA® FIX generates a thick, stable foam that:

• Clings to vertical surfaces — allowing 20–30+ minutes of contact time on walls and ceiling structures
• Penetrates dried biofilm — the extended contact time allows alkaline builders to break down hardened organic deposits that shorter-contact cleaners cannot dissolve
• Lifts heavy soiling — encapsulates manure, grease, and feed residues, lifting them from the surface for easy rinsing
• Reaches difficult areas — foam penetrates cracks, crevices, joints, and behind equipment where spray jets cannot reach

This foam-cling mechanism makes EWA® FIX significantly more effective than standard cleaners on heavily contaminated vertical surfaces — which are the most challenging areas in poultry and pig production buildings.

Heavy-Duty Formula and Foam Cling Technology

The defining characteristic of EWA FIX Bangladesh is its advanced foam-generating technology. When mixed with water and air through a foaming lance or foam generator, EWA® FIX produces a thick, shaving-cream-like foam.

Why is foam so important? The science of cleaning relies on four factors (known as the Sinner Circle): Chemical Action, Temperature, Mechanical Action, and Time. On a vertical surface, like a shed wall, a standard liquid cleaner will run down to the floor in seconds, failing to provide enough contact time to break down the dirt. EWA® FIX’s foam matrix adheres tenaciously to vertical walls, ceilings, and undersides of equipment. It literally "clings" to the dirt, maintaining chemical contact for 20 to 30 minutes.

Breaking Down Complex Organics

EWA® FIX is heavily fortified with sodium hydroxide (caustic soda) and high-performance wetting agents. This heavy-duty alkaline base is specifically targeted at saponifying thick layers of animal fat and breaking down complex protein chains found in dried blood and feces. As the foam slowly collapses over its 30-minute dwell time, it actively pulls the dissolved dirt down with it, doing a significant portion of the mechanical work for you.

Usage with Foam Lances and Pressure Washers

To achieve the optimal results, EWA® FIX must be applied using specialized equipment. A pressure washer equipped with a foam injector or a dedicated foam lance is required.

• Dilution: Generally applied at a 2% to 5% concentration at the lance nozzle, depending on the severity of the soil.
• Application: The operator should always apply the foam starting from the bottom of the wall and working upwards. This prevents the heavy foam from sliding down wet surfaces too quickly.

Application Information

Applications of EWA® FIX: Poultry Houses, Pig Houses, and Heavily Soiled Surfaces

EWA® FIX is the ultimate solution for end-of-cycle turnaround cleaning in highly contaminated environments.

• Layer and Breeder Farms: Where birds are kept for extended periods (often over a year), organic buildup is immense. EWA® FIX cuts through 12 months of grime.
• Hatcheries: Excellent for cleaning setter rooms, hatcher baskets, and chick processing areas where fluff and meconium create sticky residues.
• Slaughterhouses / Processing Plants: Highly effective at removing fats and blood from abattoir walls and processing lines.
• Broiler house terminal cleaning — complete building clean at end of production cycle
• Pig farrowing unit cleaning — heavy grease and manure in farrowing crates
• Layer house cleaning — cage structures, manure belts, collection pits
• Hatchery cleaning — incubator rooms, setter equipment, trolleys
• Food processing areas — food plant receiving areas, kill lines (external areas)
• Heavy equipment cleaning — feed mixers, augers, conveyors with heavy grease buildup

POLYCLEAN — Concentrated All-Purpose Farm Cleaner

POLYCLEAN is a versatile, concentrated all-purpose cleaning ingredient designed for broad application across all types of farm facilities. Its formulation delivers excellent cleaning performance across multiple soil types — making it ideal for farms that want a single, flexible cleaning ingredient that covers diverse cleaning tasks without requiring multiple products. 

Farm operators who manage massive, multi-shed complexes require a solution that balances exceptional cleaning power with strict economic efficiency. POLYCLEAN is designed to meet this exact need. As a highly concentrated, all-purpose cleaner, POLYCLEAN delivers outstanding broad-spectrum soil removal at a highly competitive cost-per-litre in-use.

The POLYCLEAN Formulation Advantage

POLYCLEAN contains a balanced blend of alkaline builders, non-ionic and anionic surfactants, and chelating agents. This combination provides:

• Multi-surface compatibility — effective on concrete, metal, wood, plastic, and rubber
• Multi-soil cleaning — removes protein (manure, blood), fat (grease), carbohydrates (feed), and mineral deposits
• Rinsing performance — the surfactant system rinses cleanly without leaving residue
• Water hardness tolerance — chelating agents prevent calcium and magnesium in Bangladesh's hard water from reducing cleaning efficacy
• Cold water performance — effective even without heated water, important for large-scale farm cleaning operations

Concentration Options and Economic Efficiency

The defining feature of POLYCLEAN agro BD is its concentrated nature. Because it contains minimal water in its packaged state, buyers are paying for pure, active cleaning chemistry, reducing freight and storage costs.

• High Dilution Ratios: POLYCLEAN can be diluted to ratios as high as 1:100 or 1:200 (1% to 0.5%) for light to moderate daily cleaning tasks.
• Cost-per-Litre Comparison: When farm procurement managers calculate the in-use cost of POLYCLEAN versus cheaper, ready-to-use detergents, POLYCLEAN consistently proves to be significantly more economical. You use far less chemical per square meter of shed space, making it highly viable for the large commercial poultry operations prevalent in Bangladesh.

Concentration and Cost Efficiency

POLYCLEAN's high concentration provides excellent cost-per-litre economics for large farm operations. At standard dilution (2–3%), a single 25-litre drum of POLYCLEAN yields 833–1,250 litres of ready-to-use cleaning solution — providing comprehensive cleaning coverage for medium to large farm facilities at competitive cost.

Broad-Spectrum Soil Removal

While some cleaners target specific types of dirt, POLYCLEAN is formulated to be a broad-spectrum agent. It features a synergistic blend of non-ionic surfactants that are incredibly effective at emulsifying oils, greases, carbohydrates, and proteins.

• Emulsification: POLYCLEAN works by surrounding oil and grease particles with surfactant molecules, lifting them off the surface and suspending them in the water. This prevents the dirt from redepositing onto the clean surface during the rinsing phase.

Application Information

Applications of POLYCLEAN: General Cleaning Across All Farm building  Types

Due to its balanced chemical profile, POLYCLEAN is safe for use across a wide variety of agricultural settings.

• Aquaculture: Safe and effective for scrubbing down empty fish hatcheries, fiberglass tanks, and aeration equipment before disinfection. (For more on aquatic health, see our guide on water treatment and feed additives).
• Farm Equipment Maintenance: Ideal for cleaning tractors, feed mills, silos, and farm implements without causing rapid corrosion to painted metal surfaces. feeding equipment, water delivery systems, cages, crates
• Footbaths and Boot Washing: An excellent pre-wash detergent for boot scrubbing stations located at the entrance of biosecure zones.
• All farm building types — poultry, dairy, pig, aquaculture, mixed farming
• Vehicles and transport — animal transport vehicles, farm utility vehicles
• Processing facilities — product washing and grading areas
• Site sanitation — footbaths, wheel wash stations, entry points
• General farm maintenance cleaning — year-round routine cleaning tasks

EWA® FOAM ULTRA — Ultra-Foaming Farm Cleaner

EWA® FOAM ULTRA is the most powerful foaming cleaner in the ZHM agro cleaning range, engineered for the most challenging cleaning situations in intensive animal production facilities. It is specifically formulated for broiler houses, pig finishing units, and other high-density animal production facilities where soiling is extreme — heavy manure accumulation, thick biofilm, dried-on blood and fat from processing areas, and aged organic deposits that have resisted standard cleaning.

There are situations on a farm where standard heavy-duty cleaners are pushed to their absolute limits. In scenarios involving neglected facilities, extreme disease outbreaks, or areas with massive fat and protein accumulation, farm managers must deploy the highest tier of cleaning chemistry. EWA® FOAM ULTRA is ZHM Group's premium, ultra-foaming farm cleaner, engineered for the most difficult biosecurity challenges.

The Ultra-Foam Formula and Anti-Soil Penetration

What sets EWA® FOAM ULTRA apart from EWA® FIX is the density and microscopic structure of the foam it generates. Utilizing advanced polymer-based surfactant technology, the foam created by EWA® FOAM ULTRA is incredibly tight and dense, resembling heavy whipped cream.

• Anti-Soil Penetration: When applied over heavy, porous soils (like dried litter on concrete), the ultra-foam doesn't just sit on the surface; it actively penetrates the microscopic pores of the soil matrix. It disrupts the electrostatic bonds holding the dirt to the floor.
• Unmatched Dwell Time: EWA® FOAM ULTRA boasts an extraordinary cling capability, capable of remaining on smooth vertical surfaces (like plastic wall panels or insulated sandwich panels) for upwards of 45 to 60 minutes without breaking down. This prolonged chemical exposure is devastating to biofilms.
• Full surface coverage — even application across all surfaces including ceilings, upper wall sections, and complex structural elements
• Deep biofilm penetration — extended alkaline contact time disrupts and dissolves mature biofilm communities that have built up over multiple production cycles
• High-pressure compatibility — formulated for use with high-pressure foam application systems for rapid coverage of large buildings

High-Pressure Application and Visual Coverage

Because the foam is brilliantly white and highly stable, it provides the cleaning operator with perfect visual confirmation of coverage. In the dark, dusty environment of a poultry shed, it is easy to miss spots. The thick white blanket of EWA® FOAM ULTRA ensures that every inch of the wall, ceiling, and equipment is clearly treated, ensuring zero gaps in the biosecurity protocol.

When to Use EWA® FOAM ULTRA

EWA® FOAM ULTRA is the right choice when:

• Terminal cleaning after disease outbreak — when pathogen load is suspected to be high
• Heavily soiled broiler houses — with thick, dried-on manure crusting on floors, walls, and equipment
• Pig finishing houses — with heavy fat and manure accumulation, particularly in high-density production
• Buildings with long inter-cleaning intervals — where biofilm has had extended time to develop
• First clean of a neglected or newly acquired facility — removing years of accumulated organic residue

Application Information

Applications of EWA® FOAM ULTRA : Difficult Soiling in Processing Areas

• Broiler Houses terminal cleaning (Post-Outbreak): full building foam clean between flocks. If a shed has suffered an outbreak of highly pathogenic viruses, mechanical cleaning must be flawless. EWA® FOAM ULTRA ensures that every microscopic layer of protective organic matter is stripped away, leaving a sterile-ready surface for the disinfectant.
• Pig Farms: Pig production unit deep clean. sow houses, farrowing units, finishing pens, Swine facilities are notorious for heavy grease and fat deposits. EWA® FOAM ULTRA's hyper-alkaline nature aggressively saponifies pork fats, turning them into liquid soap that washes away instantly.
• Meat Processing / Rendering Plants: Ideal for areas dealing with high volumes of blood, bone dust, and animal byproducts.
• Post-outbreak decontamination cleaning — before terminal disinfection following disease events
• Hatchery terminal clean — between hatch batches with high contamination load
• Slaughter and processing areas — floor drains, processing line external surfaces
• Aquaculture tank cleaning — algae, biofilm, and organic deposit removal from pond walls and tanks

Cleaning Protocol: Step-by-Step Biosecurity Cleaning Program for Farms

Having the best agro cleaning Ingredients is only half the battle. The other half is execution. The most expensive chemical in the world will fail if applied incorrectly. Farm managers must train their staff to follow a rigorous, step-by-step Standard Operating Procedure (SOP).

Implementing a consistent, documented cleaning protocol is essential for achieving the pathogen-reduction results that protect animal health and farm productivity. Here is the ultimate biosecurity cleaning protocol recommended for poultry and livestock operations

Step 1: Dry Removal of Gross Soiling (Day 1)

Before any water or cleaning product is applied, remove all litter, manure, feed residues, and loose organic material from the building:

• Remove all animals and remaining feed
• Sweep or shovel all litter into designated disposal areas
• Remove removable equipment (drinkers, feeders, cages) for separate cleaning
• Dry sweep floors, walls, and equipment surfaces

This step reduces the organic load that cleaning products must deal with — dramatically improving their efficacy and reducing product usage.

Step 2: Pre-Soaking (Day 1–2)

Apply diluted POLYCLEAN or PL56 at 2–3% to all building surfaces:

• Apply from the top of the building downward (ceiling → upper walls → lower walls → floors)
• Ensure complete coverage of all surfaces
• Allow 30–60 minutes contact time to begin softening dried-on organic matter

For heavily soiled surfaces: apply EWA® FOAM ULTRA foam at 3–6% dilution. Allow 45–60 minutes dwell time before moving to Step 3.

Step 3: Mechanical Cleaning with High-Pressure Washer

Using a high-pressure washer (80–150 bar, minimum 15 litres/minute flow):

• Wash from ceiling → walls → floors
• Direct jet into corners, crevices, under-slab areas, and equipment joints
• Apply EWA® FIX foam at 2–5% during this stage for walls with persistent soiling
• Ensure all surfaces are visibly clean before proceeding

Step 4: Second Application for Stubborn Soiling

For areas with persistent soiling after initial washing:

• Apply EWA® FOAM ULTRA at higher concentration (5–8%)
• Allow 45–60 minutes dwell time
• Re-wash with high-pressure water

Step 5: Clean Equipment Separately

Remove all feeders, drinkers, cages, and other equipment:

• Soak in diluted PL56 or POLYCLEAN (2–3%) for 30–60 minutes
• Brush clean and rinse thoroughly with high-pressure water
• Allow to dry completely

Step 6: Final Rinse

Thoroughly rinse all building surfaces with clean water to remove all cleaning product residues — cleaning product residues can neutralise the disinfectant applied in the next step.

Step 7: Drying (Critical)

Allow the building to dry completely — minimum 12–24 hours depending on ventilation and ambient conditions. Wet surfaces dramatically reduce disinfectant efficacy and contact time.

Step 8: Disinfection

Only after the building is thoroughly clean and dry should disinfectant be applied. ZHM Group also supplies a complete range of agro disinfection products including OXYKOL®, EWAZID® SHIELD, BIOVX®, and ALDEKOL® for the disinfection step. See our Agro Disinfection Products Bangladesh guide for disinfectant selection.

Cleaning Before Disinfection — Why Sequence Matters

To reiterate a crucial scientific principle that governs farm hygiene: Cleaning and Disinfection are two entirely separate chemical processes that must happen in a specific sequence.

Many farm operators try to save time by skipping the detergent phase and simply spraying a high concentration of disinfectant over unwashed floors. This is a critical failure in biosecurity.

The Chemistry of Neutralization: Disinfectants are biocides; they are highly reactive chemicals designed to destroy living cells. When a disinfectant (like a quaternary ammonium compound or iodine) comes into contact with organic matter (feces, soil, blood, wood shavings), it immediately reacts chemically with the proteins and lipids in that matter.

If there is a layer of manure on the floor, the disinfectant "burns itself out" by oxidizing the manure. By the time it penetrates the top layer of dirt, its chemical energy is completely spent. The millions of bacteria and viruses hiding beneath that layer of dirt survive untouched. When the next flock of day-old chicks is introduced, they immediately encounter these surviving pathogens.

By applying an alkaline detergent first—like EWA FIX or POLYCLEAN—you strip away this protective organic barrier. You destroy the biofilm. You expose the naked bacteria on the bare concrete. Only then, when the surface is physically clean, can a disinfectant successfully target and eliminate 99.999% of the microbial pathogens. Proper cleaning makes your disinfection phase cheaper, faster, and infinitely more effective.

Bangladesh farm managers sometimes ask: "Can I skip cleaning and just apply a stronger disinfectant?" The answer, based on both microbiological evidence and regulatory requirements, is definitively no. Here's why:

Organic matter inactivation: Tests demonstrate that Salmonella contaminated with only 1% organic matter requires 1,000 times more disinfectant to achieve the same kill rate as Salmonella on a clean surface. In a dirty broiler house, achieving effective disinfection without cleaning first is practically impossible.

Biofilm protection: Bacterial biofilm — the protective slime layer that develops on farm surfaces within days — is resistant to disinfection. Alkaline cleaners are required to break down and physically remove biofilm before disinfectant can access the bacteria within it.

Cost efficiency: Disinfectants applied to dirty surfaces are consumed reacting with organic matter before they can kill pathogens — wasting expensive disinfectant with minimal biosecurity benefit. Proper cleaning first dramatically improves disinfectant cost efficiency.

Regulatory and auditing requirements: Bangladesh DGDA, international food safety standards (GLOBAL G.A.P., BRC), and export market requirements all mandate documented cleaning validation before disinfection as part of farm biosecurity management plans.

Frequently Asked Questions (FAQ)

What is the difference between PL56 and EWA® FIX agro cleaners?

PL56 is a multi-purpose alkaline detergent designed for general farm cleaning tasks — routine cleaning of buildings, equipment, and vehicles where soiling is moderate. It is typically applied by pressure washer or as a soak without foam application. EWA® FIX is a heavy-duty alkaline foam cleaner specifically engineered for heavily soiled surfaces — particularly vertical surfaces like poultry house walls, cage structures, and pig house walls. Its advanced foam cling technology holds the cleaner in contact with vertical surfaces for 20–40 minutes, enabling penetration and removal of dried-on manure, biofilm, and grease deposits that standard cleaners cannot reach. For routine maintenance cleaning, use PL56. For terminal cleaning and heavily soiled surfaces, EWA® FIX delivers superior performance.

How do I clean a poultry house between flocks in Bangladesh?

The recommended between-flock cleaning protocol for Bangladesh poultry houses has eight steps: (1) Remove all remaining birds and feed; (2) Dry remove all litter and manure; (3) Remove and separately clean all feeders and drinkers; (4) Pre-soak all building surfaces with POLYCLEAN or PL56 at 2–3% dilution, allowing 30–60 minutes contact time; (5) For walls and cage structures, apply EWA® FIX foam at 2–5% and allow 20–40 minutes dwell time; (6) High-pressure wash all surfaces from ceiling to floor; (7) For persistent soiling, apply EWA® FOAM ULTRA at 3–6% and re-wash; (8) Final clean water rinse, allow to dry completely (12–24 hours minimum) before applying disinfectant. ZHM Group supplies all four cleaning products and can provide a customised cleaning protocol for your specific farm setup.

What concentration should I use for EWA® FOAM ULTRA in poultry cleaning?

For standard between-flock cleaning of moderately soiled broiler houses, use EWA® FOAM ULTRA at 3–4% dilution (30–40ml per litre). For heavily soiled houses with thick manure deposits, dried-on organic matter, or mature biofilm, increase to 5–6% dilution (50–60ml per litre). For post-disease outbreak terminal cleaning where maximum decontamination is required, use 6–10% dilution. Always pre-remove gross soiling (litter, manure) before applying EWA® FOAM ULTRA — this ensures the product's cleaning action is focused on penetrating residual biofilm and fine organic deposits rather than being consumed by gross soiling. Allow a minimum 45–60 minutes dwell time before high-pressure rinsing for optimal results.

Are ZHM Group's agro cleaning products safe for use around livestock and poultry?

ZHM Group's agro cleaning products — PL56, EWA® FIX, POLYCLEAN, and EWA® FOAM ULTRA — are professional agricultural cleaning products that must not be applied in the presence of animals. All animals must be removed from the facility before any cleaning product is applied. Once cleaning is complete and all product has been thoroughly rinsed away, the facility must dry completely and be ventilated before restocking with animals. All four products are supplied with full Safety Data Sheets (SDS) detailing handling precautions, required personal protective equipment (PPE — gloves, eye protection, appropriate footwear), first aid measures, and environmental disposal guidance. Follow all SDS instructions for safe and effective use.

Can POLYCLEAN be used with a high-pressure washer?

Yes — POLYCLEAN is fully compatible with high-pressure washing systems and delivers excellent results when applied through a chemical injector on a pressure washer. For high-pressure application, dilute POLYCLEAN at 2–3% and apply through the chemical injection system. The high-pressure water delivery enhances mechanical removal of loosened soiling after the POLYCLEAN has had 15–30 minutes of contact time to penetrate organic deposits. For best results, apply POLYCLEAN as a pre-soak (either manually or through a low-pressure chemical applicator) and allow contact time before switching to high-pressure wash mode. This pre-soak then high-pressure wash sequence consistently delivers superior cleaning results compared to direct high-pressure application without pre-soaking.

Does ZHM Group supply agro cleaning products in bulk for large poultry farms in Bangladesh?

Yes — ZHM Group supplies all four agro cleaning products in bulk quantities suitable for large-scale commercial poultry and livestock farming operations in Bangladesh. We supply 25-litre containers for smaller farms and trial orders, 200-litre drums for medium-scale operations, and IBC (Intermediate Bulk Container) quantities for large commercial farm operations.
