The most effective method is circulation for large systems or components likeboilers, evaporators, condensers, heat exchangers and generally closed systems that have the capability to circulate at a temperature of approximately 40-60°C, for 6-12 hours and solutions of 10-40% of Drain Scale Remover in water. Keep in mind that the strength of the solution is analogous to the degree of  deposition of scale .

In case of small components , the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease, sludge or carbonized oil, then first of all  clean the system with  RXSOL OB 1005.

Drain Scale Remover  should be mixed with fresh water  to form a  solution  of  10-30%, depending  on  the extent of scaling.

After using Drain Scale Remover  it  is essential to  thoroughly  rinse all metal surfaces at least once   with  a 0.5% solution of  Alakleen Liquid or Liquid Soap in  fresh  water.  This  solution  should  be  circulated for 2-4   hours  or  until  an acceptable pH value is obtained. This  will  neutralize any remaining acidity   &  passivate  steel  surfaces. Drain Scale Remover should not be used  on  Aluminium, Zinc, Tin,  or  any  Galvanized  Surfaces  for  which  a special grade cleaner should be used.
