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…

  1. 1

    A cleaning composition for stainless steel consisting essentially of about 9% to 12% by weight of a halogenated C.sub.2 hydrocarbon having 2 L to 4 atoms of a halogen of the group consisting of chlorine and bromine per molecule; about 3% to 6% by weight of a fatty acid having 10 to 20 carbon atoms per molecule; about 3% to 5% by weight of an alkanol amine having 2 to 12 carbon atoms and 1 to 2 amino groups per molecule; about 25% to 30% by weight of a water-soluble C.sub.1 to C.sub.4 alkyl…

2Description

Background of the Invention

It is known to incorporate trace amounts of soaps in dry cleaning solutions along with minimum amounts of water. In U.S. Pat. No. 3,701,627 by Grunewalder, there is disclosed a process for cleaning soiled textiles by treatment with a clear water-containing organic solvent mixture of 20% to 40% by volume of a halogenated hydrocarbon having from 1 to 2 carbon atoms, from 55% to 70% by volume of a…
