FOR TANK CLEANING

RECOMMENDATION : 0.2% TO 100%

FIELD :-
specially designed for  removal of rust from any steel surface area and rust stain from Brass , Copper , S.S wood, ceramic and aluminium surfaces, painted or not . And act as  surface brightner.

Procedure for Use :-

• RXSOL-20-1011-210 is highly concentrate
• Dilute in water (always use plastic jar and RXSOL-20-1011-210 should be added to  water  never add water to (RXSOL-20-1011-210.)
• Surface should be sound clean and free from oil, grease, dirt etc.
• Diluted materials apply on rusted area for 15 to 20 minutes then wash off with water repeat if necessary.
  (For stubborn rusted stains.)

NOTE :-
For steel surfaces; remove oil, grease and old paint. Wet down entire surface with neat Metal Clean Bright- Rx and allow to dry. Second wash may be necessary. Surface should have a grey/white appearance when the Metal Clean Bright- Rx is dry. Steel surfaces will have a resistance to rust and will render a good base for paint.For removal of rust stains on painted surfaces and wood, Metal Clean Bright Rx should be applied at full concentration  for heavy stains, or diluted to 20-50% for light stains. Allow to soak for 15 to 30 minutes and wash off with water. A second application may be necessary to remove the stubborn stains.

Spraying Direction :-
Using an empty / clean 210 liter drum, fill with 190 liter of fresh water and add 20 liters of Metal Clean Bright Rx  This makes a 10% solution, which can be sprayed onto areas in coated tanks where rust stains are showing and over actual rusted areas.  Once spraying is completed, wait 20-30 minutes and fresh water rinse with lots of water, if possible use butterworth machines for a more efficient result.  This method can be used in stainless tanks to “freshen up” the look of the stainless materials.  Make sure to rinse the tank very well, as residual detergent within the Metal Clean Bright Rx  will show up in a Wall Wash.
Injection – Not suitable.

Re-circulation :–
When hand spraying is inadequate (too much area to cover), prepare a 2% - 5% solution in the tank using fresh water, heat solution to 50o C, then circulate the solution through butterworth machines for 3 x 45 minutes drops minimum.  When using fixed machine recirculate for a minimum of 3 cycles.  Rinse out the tank using hot seawater 85o C for 2 hours making sure that there is no form remaining in the water at the pumpstack drain cock.  After the hot wash, the tank must be rinsed with fresh water and dried.

* If the mixture is allowed to overheat, it will soften epoxy / phenolic coating.
* Use a strainer at the pumpstack when circulating any solution.
