Why De-scaling?

Vanchem provides effective de-scaling solutions for the removal of scale buildup in industrial washer system.


Vanchem Performance Chemicals offers our descaler product, VANCHEM RSH. It is an inhibited hydrochloric acid based product designed for effective de-scaling on mild steel, stainless steel and some brass equipment. Water hardness, co-precipitated oils or greases and phosphate precipitates are causes of scale buildup. VANCHEM RSH removes all these scales.

De-scaling washers is necessary when inorganic scale and some organic contaminants are not removable with basic cleaning solutions. De-scaling restores steel surfaces and piping (metal or plastic) to their original condition.

Scale buildup generally affects heat transfer and fluid flow in piping. Vanchem’s de-scaling products remove scale by rapidly dissolving existing deposits of metallic oxides, carbonates, sulphates, and silicate scale formations. The application of de-scaling depends on the conditions and levels of existing buildup. Vanchem’s de-scaling product, VANCHEM RSH, contains special wetting agents, which aid in the removal of scale buildup and oils.

Vanchem has the capability of bulk chemical de-scaling. Bulk de-scaling is typically used for large automotive phosphate tanks. Vanchem brings in tanker loads of nitric acid based de-scalers for phosphate tanks and tanker loads of VANCHEM RSH for cleaner tanks. De-scaling acid is circulated for ten to twenty hours, depending on the levels of buildup. We recommend semi-annual de-scaling for large automotive zinc phosphate and alkaline cleaner tanks.

Vanchem is highly driven to meet the highest quality standards in formulating de-scaling chemical compounds for industry. The cost effective and high-grade solutions meet our customers’ strict standards. For more information, contact us at our corporate headquarters in Burlington Ontario.
