Recommended Cleaning Procedure

1. Initial Washing: Flush cargo tanks with cold water to remove loose residues and reduce the risk of polymerization of drying oils.

2. Chemical Cleaning: Prepare an appropriate dilution of RXSOL HCF Remover according to the cargo residue, tank coating and approved cleaning procedure.

3. Recirculation: Circulate through tank cleaning machines, ensuring suitable filtration or straining.

4. Spot Cleaning: For persistent residues, apply the cleaner directly and allow approximately 10–45 minutes of contact without letting it dry.

5. Final Rinsing: Wash thoroughly with fresh water, inspect the tank and confirm that residues and foam have been removed.

The published application instructions also describe warm-water washing at approximately 60°C for suitable systems. Temperature limits must be checked against tank coating specifications.

Spraying Method:-Using HCF as delivered in drums, spray onto areas where residue remains following rough washing leave for 10-45 minutes (but do not allow to dry), then butterworth at maximum pressure and warm water 60^oC for at least 3 hours, checking that there is no foam remaining in the final stages.  Inspects tanks(s) and if desired result has been achieved fresh water rinse and dry.

** Make sure to take all safety precautions are followed when handling / spraying HCF **

Injection Method:– Not applicable.

Re-circulation Method:–Fill tank with fresh water and heat up to warm 50^oC .  IF a drop line is available on the tank line system, then start to circulate the water and add the required amount of Caustic flakes and HCF to make a 2.5% solution.  A stronger solution can be made, but be advised that too much Caustic and too high temperature will result in white powder all over the tank.  Under normal circumstances, between 2.5% and 4.5% will be sufficient strength.  If there is no drop line, then lower butterworth hoses into the tank from the pump stack header without machines attached and circulate through these hoses while you fill the solution material. 

**Use a strainer at the pump stack when circulating any solution.** 

Tank Lining– Stainless / Epoxy / Phenolic / Zinc-silicate.

Using-Procedure:-First of all flush the system with cold water to prevent evaporation rates and polymerization then the most economical method of using RXSOL-20-2007-020  is by direct injection followed by recirculation washing, using tank cleaning machines.
