For years mineral acids like hydrochloric and sulfuric acid have been used in metal finishing constantly releasing fumes which can be corrosive to equipment and parts. Acid salts were developed to increase the effect of acid treatments, but in a safer manor.
Acid salt is good for the bottom line, equipment, operator safety, and water treatment in many applications. This results in an operating cost reduction while improving health and safety concerns. Newer developments include “liquid” versions of acid salt if the convenience of pumping the solution is desired, while many of the benefits of salt are maintained.
