ABSTRACT:
Stable, essentially non-toxic, clear cleaning solutions for a variety of metals, especially stainless steel, are disclosed characterized by exhibiting a combination of solvent actions to dissolve both water-soluble and water-insoluble dirt accumulations and leave the metal surfaces in a bright, polished and clean condition with the use of a wiping action. Basically the compositions contain a low molecular weight chlorinated hydrocarbon solvent and a sufficient amount of an amine soap of a long-chain fatty acid to form a clear aqueous solution with or without certain co-solvents such as butoxyethanol, soluble in both the aqueous and non-aqueous phases, and selected optical brighteners and streak-reducing agents. An illustrative composition contains about 9% to 12% by weight of the chlorinated solvent, 3% to 6% by weight of the fatty acid, 3% to 5% by weight of the amine, 25% to 30% by weight of a water-soluble alkyl glycol ether with the balance being water. Other embodiments are disclosed.
