Polykleen Dry Acid is a properly balanced formulation of organic acids, inhibitor, and surfactants. It is non-hygroscopic, non-volatile and gives no obnoxious or corrosive fumes. When in solution, it has an acid strength equal to that of strong acids such as hydrochloric and sulfuric acids. It provides the utmost safety in handling to the user. Any spillage is swept up easily as if it were salt. This handling ease and safety of Polykleen Dry Acid and its lower corrosiveness enable it to replace the most common liquid type acidic compounds as a water scale and rust remover for heat exchangers, boilers, evaporators and other equipment.
