Safe Scale Remover with Indicator

Safe Scale Remover with colour Indicator - Red to Yellow
RXSOL-22-2210-200  is mixed with fresh water 3 to 20 percent ( 3 Ltr to 100 Ltr water ) depending on deposition of scaling.

The most effective method is circulation for large systems or components like boilers, 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 5-40% of RXSOL-22-2210-200 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 degreaser  RXSOL-10-1005. RXSOL-22-2210-200 should be mixed with fresh water to form a solution of 10-30%, depending on the extent of scaling.  

PRECAUTION :::it is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of  RXSO-20-2005  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.
