Directions for Use and Dose Rates

The most effective descaling is accomplished by circulation. In the case of small components, the soak method in an immersion bath can be used. Depending on the extent of scaling, use a solution of 2.5-10% Star Power Acid Liquid, the solution will have a white colour which disappears when the solution is neutralised. Whenever possible, the solution should be heated to 60°C. Neutralised solutions can be reactivated by adding more Star Power Acid Liquid until the white colour reappears. This should not be done more than twice.

Star Power Acid Liquid should not be used on aluminium, zinc, tin or galvanised surfaces. Descaling of Boilers, Descaling of Diesel Engine, Cooling Water Systems, Condensers, Evaporators, Clarifiers, and Heat


The strength of the acid can be enhanced by adding 1 part sodium chloride (common salt) to 20 parts of Star POWDER ACID. This enhancement of the cleaning solution, however, should not be used when descaling diesel engine cooling water systems.
