Descaling Liquid – liquid acid for removal of scale and rust
Descaling Liquid is a liquid acid containing descaling accelerators, corrosion- inhibitors and wetting agents.
Directions for Use and Dose Rates The most effective descaling is accomplished by circulation for large systems or components. In the 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 carbonised oil, then pre-cleaning with Seaclean or Enviroclean is necessary. Descaling Liquid should always be used in plastic bucket. Acid should always be added to water, and never the reverse. Descaling Liquid should be mixed with fresh water to form a solution of 10-30%, depending on the extent of scaling. After using Descaling Liquid it is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of Alkalinity Control 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 and passivates steel surfaces. Descaling Liquid should not be used on aluminium, zinc, tin, or any galvanised surfaces for which a special grade cleaner should be used.
