Directions for use

  1. Mix solutions of MARCLEAN MB40 either in tank bottom or void space.
  2. Dilution rate with water between 4% and 10%, depending upon light or heavy contamination. Recent experience has shown that a 8% - 8.5% solution secures successful cleaning. 
  3. Do not use the entire quantity of MARCLEAN MB40 in one solution for all tanks to be cleaned.
  4. Save a few drums (2 - 3) to “boost” the solution for cleaning the last 20% - 25% of the tanks to be cleaned.
  5. The solution may be used at ambient temperature, however, it is suggested that an increase of the cleaning temperature to maximum 80°C will enhance the cleaning ability and shorten the cleaning time. 
  6. Proceed to recycle the cleaning solution through the tank washing system for a period of two hours minimum per machine drop. Usually a cleaning time of 4 hours per tank will prove sufficient.
  7. At completion of chemical application begin washing down with water, using maximum pressure available 8. Inspect tank surfaces and if there remain some stains, spot clean with undiluted MARCLEAN MB40 directly on the stained area. Allow a reaction time of 30 minutes and then rinse with fresh water.

Can be used on iron, stainless steel and copper without any problems. Excellent product to be used for removing light rust from iron and steel surfaces. It also cleans and brightens aluminium and copper, rust stains on painted surfaces, porcelain, terrazzo, ceramic tiles, wood, etc.
