Cleaning chemicals are used every day onboard vessels, but they should not be treated as ordinary consumables. The wrong cleaner can damage coatings, create crew safety risks, contaminate cargo areas, complicate waste handling or create compliance problems under MARPOL requirements.
For technical buyers, HSEQ teams and chief officers, marine cleaning chemicals procurement MARPOL is about selecting products that are effective, documented, safe to handle and suitable for the vessel’s operating environment.
A vessel may need hold cleaning chemicals, tank cleaning chemicals, deck cleaners, degreasers, galley cleaners, cabin hygiene products, multipurpose detergents, descalers, disinfectants, bilge area cleaners and spill response products. Each category has different documentation, storage, compatibility and disposal considerations.
AVS Global Ship Supply & Catering supports ship owners, ship managers, technical buyers and HSEQ teams with marine chemicals, technical stores, deck consumables, cleaning chemicals and vessel supply coordination across international ports.
For regulatory context, see MARPOL. For cleaning chemical, detergent and vessel maintenance supply requests, submit your requirement through Quick Quote.
Marine cleaning chemicals are used in different areas of the vessel. A product that works well in a galley may not be suitable for cargo hold cleaning. A deck degreaser may not be appropriate for tank cleaning. This is why procurement teams should separate cleaning chemicals by application before requesting a quote.
Hold cleaning chemicals are used to remove cargo residues, dust, stains, grease, mineral deposits or contamination from cargo holds. They are especially relevant for bulk carriers that change cargo type between voyages.
Common hold cleaning chemical types include:
When requesting hold cleaning chemicals, buyers should specify the previous cargo, next cargo, hold coating type and cleaning objective.
Tank cleaning chemicals are used for cargo tanks, fuel-related spaces, chemical tankers, product tankers and other vessel areas where residues must be removed before inspection, repair or cargo change.
Tank cleaning requirements may depend on:
Tank cleaning products require careful technical review because they may be linked to cargo compatibility, enclosed space safety and waste handling procedures.
Deck and machinery space cleaning products support daily vessel maintenance. They may include detergents, degreasers, oil removers, descalers, rust removers and multipurpose cleaners.
Common categories include:
These products should be selected with coating compatibility, crew exposure, slip risk and waste handling in mind.
Galley and accommodation cleaning chemicals are used for hygiene, food preparation areas, cabins, laundry, bathrooms and common spaces. These products are closer to crew welfare and food hygiene management than heavy-duty cargo cleaning.
Typical categories include:
For food preparation areas, product selection should support hygiene procedures. For broader food safety context, buyers may also review HACCP and ISO 22000.
A vague RFQ such as “cleaning chemical” often leads to wrong quotations. Suppliers need the application, surface, residue type and documentation expectation to quote accurately.
A strong RFQ should include:
This structure improves quotation accuracy and reduces unsuitable substitutions.
Hold and tank cleaning chemicals should be procured with more technical detail than general-purpose cleaners. The wrong product can damage coatings, leave residues, fail inspection or create safety hazards.
For cargo holds, the previous and next cargo are essential. A cleaner suitable after coal may not be the best choice after cement, grain, sulphur, petcoke, fertilizer or mineral cargo.
The RFQ should state:
If the next cargo is sensitive, cleaning standards may be stricter.
Tank cleaning chemical selection should consider cargo properties, residue behaviour and crew safety. Some residues may create flammable vapours, toxic exposure or chemical reaction risks.
Tank cleaning RFQs should include:
Chief officers, chief engineers and HSEQ teams should coordinate before approving tank cleaning chemicals.
Some cleaning chemicals can damage epoxy coatings, zinc silicate coatings, aluminium, rubber seals, painted surfaces, stainless steel, brass, copper or plastic components.
Buyers should ask for:
If coating damage occurs, the cost can be much higher than the cleaning chemical price.
Depending on product type and vessel procedure, documentation may include:
Documentation should be requested before delivery, not after the vessel has already started cleaning.
Galley, cabin and general-purpose cleaners are used more frequently than cargo cleaning chemicals. Because they are handled by crew in daily routines, safety, labelling, dilution and storage are especially important.
Galley cleaning products should remove grease, food residues and surface contamination without creating unnecessary crew exposure or residue risk on food-contact areas.
Common galley products include:
For galley use, buyers should confirm whether the product is suitable for food preparation areas and whether rinsing is required.
Accommodation cleaners support crew welfare and daily hygiene. These products should be easy to use, clearly labelled and safe when used according to instructions.
Common accommodation cleaning products include:
Strong fragrance, poor ventilation or incorrect dilution may affect crew comfort, so procurement should consider usability as well as price.
Disinfectants should be selected carefully because they may have specific contact time, dilution, storage and hazard requirements.
Before buying disinfectants, confirm:
Not every cleaning product is a disinfectant. The product claim should match the intended use.
General-purpose cleaners are useful for routine cleaning, but they should not replace specialized products when the application requires a specific chemical.
A general-purpose cleaner may be suitable for:
It may not be suitable for:
Procurement teams should define the use case clearly.
MARPOL Annex V addresses prevention of pollution by garbage from ships. It generally prohibits the discharge of garbage into the sea, except under limited circumstances defined in the Annex.
For vessel cleaning chemicals, the key issue is how cleaning agents, additives and residues in wash water are handled.
Cleaning operations may produce wash water containing:
Depending on the cleaning operation, disposal may involve shipboard procedures, reception facilities, garbage management plans, cargo residue rules or other pollution prevention requirements.
Cleaning chemical procurement should therefore consider not only product performance but also environmental classification and waste handling.
Under MARPOL Annex V, cleaning agents or additives in wash water must be assessed carefully, especially when cargo residues or external surface wash water are involved.
Buyers and HSEQ teams should check whether the product:
This is especially important for cargo hold washing and deck wash operations.
Cargo residues may be classified as harmful to the marine environment depending on the cargo and applicable criteria. If harmful residues are present, discharge rules become stricter.
For hold cleaning, procurement teams should coordinate with vessel staff to confirm:
The cleaning chemical supplier may provide product information, but the vessel operator remains responsible for correct onboard compliance decisions.
Cleaning chemical procurement should align with the vessel’s garbage management procedures.
Records may include:
A well-documented cleaning process supports HSEQ review and port inspection readiness.
Cleaning chemicals must be stored and handled correctly onboard. Poor storage can lead to leakage, reaction, label loss, crew exposure or product failure.
Cleaning chemicals should be stored in designated areas with clear labels and secure packaging. Incompatible products should not be stored together.
Good storage practices include:
Storage rules should follow the product SDS and vessel procedures.
Some cleaning chemicals can react dangerously when mixed. For example, acid-based cleaners, chlorine-based products, ammonia-based products and strong alkalis should be managed carefully.
Crew should avoid:
Clear labelling and crew training are essential.
The required PPE depends on the product and task. The SDS should always be the main reference.
Typical PPE may include:
For stronger tank cleaners, degreasers, acids or caustic products, PPE requirements may be stricter.
Spill response should be planned before chemicals are used.
A practical response plan should include:
Spill kits and absorbents are part of effective chemical safety management.
Many buyers now ask for lower-impact cleaning chemicals. However, “green”, “eco-friendly” or “biodegradable” claims should be reviewed carefully. Procurement teams should look for credible information, not marketing language alone.
Greener cleaning products may aim to reduce:
However, a greener product must still perform properly. A weak cleaner may require repeated application, higher dosage or longer cleaning time, which can reduce the practical environmental benefit.
Green Seal and other ecolabels can help buyers identify products that meet defined environmental and health-related criteria. These labels may consider factors such as ingredients, toxicity, biodegradability, packaging and product performance.
Procurement teams should check:
Ecolabels can support decision-making, but they do not replace technical suitability review.
Surfactants are key ingredients in many detergents and cleaners. Bio-surfactants or bio-based surfactants may reduce reliance on petroleum-derived ingredients and support lower-impact cleaning formulations.
When reviewing bio-surfactant products, buyers should check:
A green product should be both environmentally preferable and operationally effective.
Greenwashing occurs when environmental claims are vague, exaggerated or unsupported.
Buyers should be cautious with claims such as:
These claims should be supported with documentation, test data or recognized certification.
Cleaning chemicals are frequently reordered, which can make teams rely too heavily on old purchase records. But product names, formulations, regulations, vessel routes and cleaning requirements can change.
Common procurement mistakes include:
These mistakes can create operational, safety and compliance problems.
A strong RFQ should include:
This helps suppliers quote the right product and documentation.
Cleaning chemicals may be priced by liter, kilogram, drum, pail, can, carton or pallet depending on product type and packaging.
Buyers should compare:
The cheapest product per liter may not be the cheapest product per cleaning result.
AVS supports technical buyers, HSEQ teams and chief officers with vessel cleaning chemical sourcing, product clarification, documentation collection and delivery coordination across international ports.
AVS can support:
AVS helps buyers clarify product requirements before delivery, reduce unsuitable substitutions and support safer vessel cleaning operations.
Cleaning chemicals are essential for vessel hygiene, cargo readiness, maintenance and safety. But effective procurement requires more than choosing a familiar brand or the lowest price.
Technical buyers should define the cleaning application, surface, residue, quantity, documentation and MARPOL relevance before placing an order. HSEQ teams should check SDS, crew safety, storage compatibility and waste handling. Chief officers should confirm operational suitability for hold, tank, deck or accommodation use.
For greener cleaning products, buyers should look beyond marketing claims and request credible documentation, ecolabel information and performance evidence.
AVS Global Ship Supply & Catering supports ship owners, ship managers, technical buyers and HSEQ teams with marine cleaning chemicals, technical stores, documentation support and vessel delivery coordination across international ports.

MARPOL Annex V is the part of MARPOL that addresses prevention of pollution by garbage from ships. It generally prohibits discharge of garbage into the sea except under limited conditions defined in the Annex.
Yes. Cleaning agents, additives, cargo residues and wash water may be subject to MARPOL-related restrictions depending on the product, residue, cleaning operation, location and environmental classification.
A hold cleaning chemical is a product used to clean cargo holds after cargo discharge. It may remove dust, stains, grease, cargo residues, mineral deposits, odours or contamination before the next cargo.
Some eco-labelled or lower-impact cleaners can be effective, but performance depends on residue type, dilution, surface, cleaning method and contact time. Buyers should request technical data and performance evidence.
AVS can support tank cleaning chemical sourcing depending on product type, delivery port, vessel requirement, documentation needs and availability.
Typical documents may include Safety Data Sheet, Technical Data Sheet, product certificate, packing list, delivery note, invoice, batch information and proof of delivery. MARPOL or environmental declarations may be requested where relevant.
Cleaning chemicals should be stored in designated, labelled and secure areas. Incompatible products such as acids, alkalis, oxidizers or flammable chemicals should be separated according to the SDS and vessel procedures.
PPE depends on the chemical and task. Gloves, eye protection, face shield, protective clothing, apron, safety boots or respiratory protection may be required. The SDS should always be checked.
Some vessels, companies, charterers or cargo interests may maintain approved chemical lists. Buyers should check onboard procedures and company requirements before accepting substitutes.
Cleaning chemicals may be priced by liter, kilogram, drum, pail, can, carton or pallet. Buyers should compare dilution ratio, concentration and cost per cleaning operation, not only unit price.
Some cleaning chemicals can be supplied in bulk or larger packaging, depending on product type, port availability, handling capability and vessel storage arrangements.
Spills should be managed according to the SDS and vessel procedures. Crew should isolate the area, wear correct PPE, prevent entry to drains or sea, use compatible absorbents, collect waste safely and record the incident.
