The Sterlclean de-scaling system from Sterling for the removal of scale, lime and rust deposits circulates USDA-approved Sterlclean de-scaling fluid, which is non-toxic, non-corrosive, non-flammable, biodegradable and can be disposed of in normal plant sewers. The system has the ability to dissolve approximately two pounds of calcium carbonate scale per gallon while in concentrated form, says the company.  It is suitable for de-scaling heat exchangers, piping systems, molds, dies, tanks, pumps, rolls, mixing valves and more.
