This powerful cleaner is not a soap nor a detergent, but a well balanced chemical compound. It is fully rust inhibited and is safe for cleaning all ferrous and non-ferrous metals. Its minimum foaming properties give free rinsing. Contains no carbon tetrachloride or other chlorinated solvents, no naphtha, no benzenes. It is most effective for dissolving heavy deposits of oxidized waxes and polymers, thick layers of down trodden greases, baked on deposits of carbon, soot, resins, gums, oils, dyes, and hard soap scum.
