Many formulations have been proposed for removing tarnish and oxides from silver, copper, brass, and other metals. “Tarnish”, as the term is used herein, embraces the filmy discoloration of a metal surface that occurs as a result of a chemical change in the metal. Just a physical clay. An example is the formation of a sulfide or oxide film that is integrated with the metal surface and has all the indications of metallic corrosion. The prior art formulations proposed are either designed to remove stains, etc. only, or to remove stains, etc., and additionally upon exposure to normal environmental conditions. Formulated to suppress the tendency of metal surfaces to re-stain or tarnish. , thus at least partially eliminating the problem of periodic cleaning and preventing corrosion of metal surfaces.
