Tank Cleaner HD is powerful Solvent based Emulsifier, Effectively CLEANS oily greasy mud, Effectively works on Black Oil, Furnace Carbon deposited mess. RXSOL TANK CLEANER HD is blended with new generation penetrating solvent and Emulsifier to make cleaning easy and fast.

Direction to follow to achieve heavy duty TANK CLEANING for heavy fuel oil, sludge, oil, grease, wax, and paraffin removal:

1. Pre-Cleaning / Preparation

• Where operationally possible, remove free oil and pumpable sludge before chemical cleaning.

• Pre-wash the tank using warm or hot high-pressure water to remove loose contamination and expose the heavier deposits to the chemical treatment. The supplied reference similarly recommends high-pressure warm-water prewashing before application.

• Removing loose material before chemical treatment considerably improves chemical efficiency and reduces consumption.

2. Recirculation Method

• Prepare the required cleaning solution according to the severity of contamination.

• As a general starting point:

• Minimum concentration: approximately 0.5%

• For severe contamination, a stronger concentration may be required following an onboard trial.

• Circulate the cleaning solution through the tank, pipelines and associated equipment so that all contaminated surfaces receive adequate contact.

• Heating considerably improves the removal of heavy fuel oils, aged hydrocarbons and sludge.

• For difficult contamination, temperatures approaching 70°C can substantially improve cleaning performance where the tank construction, coating, cargo history and operating conditions permit.

• The reference TDS likewise specifies a minimum 0.5% solution for recirculation and reports best performance around 70°C.

• After cleaning, drain the contaminated solution and rinse thoroughly with fresh water or seawater as appropriate.

3. Rock-and-Roll Method

This method is particularly suitable for tank cleaning while the vessel is underway.

• 0.5-1.0 litre RXSOL Tank Cleaner Super S per 1,000 litres of water.
• Allow the solution to remain in contact with the bottom deposits for approximately 2–6 hours.
• This concentrated initial contact helps penetrate, soften and loosen hardened sludge and petroleum deposits.

• Increase the water level to approximately 30% of tank capacity and allow natural vessel movement to provide agitation.
• Maintain contact for approximately 1–2 days, depending upon contamination and voyage conditions.
• The supplied reference describes the same initial concentration, contact period and 30% filling stage.

• Drain → inspect → rinse → repeat if necessary.

4. Heated Soaking / Ballast Method

• For heavily contaminated fuel-oil tanks, determine the required amount of RXSOL Tank Cleaner Super S and introduce it into the tank.
• Fill the tank to approximately 75% capacity with water and provide heating where possible.
• For severe deposits, maintaining the cleaning emulsion at approximately 60°C for an extended contact period can substantially improve penetration and sludge removal.
• The reference procedure specifies maintaining the emulsion at approximately 60°C for 3-5 days where possible, followed by deballasting and repeated seawater rinsing until the discharge runs clear.
• For exceptionally heavy contamination, the treatment may need to be repeated.

5. Direct / General Degreasing

• Brushing
• Soaking
• Immersion
• Manual application
• Suitable spraying equipment
• Circulation
