Suggested Dilution Guidelines

The following table is for preliminary cleaning trials only. It is not a validated product-specific dosing recommendation.

Example: A 10% solution by volume contains 10 litres of chemical made up to a final volume of 100 litres with water, assuming the formulation is suitable for water dilution.

The final dilution must be confirmed based on cleaning performance, product chemistry, coating compatibility and manufacturer instructions.

RXSOL PCS (Coal / lime Remover) may be used concentrated or diluted with water, depending on the degree of contamination, the surface area to be treated, the desired degree of cleaning and the available downtime.Actually, the user is the best one capable to regulate the quantity and concentration to be used for the situation at hand.In any case, when the accumulation is not heavy, a 50% solution with water must be used. Otherwise,Rxsol PCS (Coal Remover). can be used undiluted especially when deposition is heavy and hard spots persist.

Cleaning Procedure

Conventional cleaning methods such as a brush,hard sponge, thick and hard broom and /or a mop can be used on heavy duty and hard stain deposits.Note that for heavy accumulations the cleaning procedure might be necessary to be repeated until the results are satisfactory. Furthermore, is important to keep in mind that 1 litre of Rxsol PCS (Coal / lime Remover) is sufficient to cover a surface area of 8–10 square meters.


NOTE ::: -- Let this product soak into the surface for 30-45 minutes. Then using a high-powered spray washer blast the surfaces until the stains and discoloration is gone.

Factors Affecting Cleaning Performance

The cleaning performance of RXSOL Coal Stain Remover depends on:

• Type and grade of coal handled.

• Duration of cargo contact with the surface.

• Thickness of accumulated deposits.

• Presence of oils, grease or other cargo contamination.

• Surface roughness and condition of the cargo hold coating.

• Cleaning solution concentration.

• Water temperature.

• Contact time.

• Washing pressure and mechanical assistance.

Older or damaged coatings may retain coal staining even after loose deposits have been removed.

Compatibility

RXSOL Coal Stain Remover is intended for compatible cargo hold surfaces.

Before application, verify compatibility with:

• Epoxy-coated cargo holds

• Polyurethane-coated surfaces

• Painted steel bulkheads

• Hatch cover coatings

• Rubber seals and gaskets

• Aluminium components

• Galvanized surfaces

Test the cleaning solution on a small, inconspicuous area before full-scale application.

Highly alkaline or solvent-containing formulations may affect certain paints and sensitive materials.

Safety & Handling

• Read the product Safety Data Sheet before use.

• Wear chemical-resistant gloves, protective clothing and suitable eye protection.

• Avoid inhalation of cleaning spray or mist.

• Provide adequate ventilation in enclosed cargo holds.

• Follow confined-space entry procedures where applicable.

• Avoid direct contact with skin and eyes.

• Do not mix with acids, oxidizing agents or other cleaning chemicals without compatibility verification.

• Prevent uncontrolled discharge of cleaning solutions and coal-contaminated wash water.

• Use suitable chemical-resistant spraying and pumping equipment.

Environmental Precaution: Cargo hold wash water must be managed in accordance with MARPOL Annex V, applicable port requirements and any cargo-residue classifications. Chemical cleaning agents must also meet the relevant discharge requirements; do not assume that wash water may be discharged overboard.

Storage & Shelf Life

Store in tightly closed, properly labelled containers in a cool, dry and well-ventilated location.

Keep away from direct sunlight, excessive heat and incompatible chemicals.

Shelf Life: To be established from the approved product stability specification.

Packing

Product: RXSOL Coal Stain Remover Packing: 25 L cans, with larger drum or IBC packing subject to confirmation.

Frequently Asked Questions

Q1. What is RXSOL Coal Stain Remover used for?

It is intended to remove coal dust, black coal stains and carbonaceous cargo residues from compatible marine cargo hold surfaces.

Q2. Can it be used for bulk carrier hold cleaning?

Yes. Cargo hold cleaning after coal discharge is its primary intended application.

Q3. Can it remove old coal stains?

It may help reduce stubborn coal staining, but results depend on deposit age, surface condition and the extent to which contamination has penetrated the coating.

Q4. Is high-pressure washing necessary?

High-pressure washing is often effective for removing loosened coal residues, although the required pressure depends on the surface and coating condition.

Q5. Can it be used on epoxy-painted cargo holds?

Only after confirming compatibility with the specific epoxy coating.

Q6. Can the product be used for petroleum coke stains?

Some cleaning methods may overlap, but petroleum coke deposits can behave differently from coal residues. A product specifically evaluated for petcoke cleaning may provide better results.

Q7. Does the product remove rust?

Coal Stain Remover is primarily intended for coal-related contamination. Rust removal may require a separate chemical treatment.

Technical Recommendations

For effective cargo hold cleaning, remove as much dry coal residue as possible before applying chemical cleaners.

Avoid applying cleaning chemicals directly over thick layers of loose cargo residue, as this can increase chemical consumption and reduce cleaning efficiency.

For cargo changeovers involving sensitive cargoes such as grain, fertilizer or other cleanliness-critical products, verify the required hold cleanliness standard and ensure all chemical residues are removed before loading.
