Was just using this on some small parts that turned our great and thought it might help someone else here and to pass on the info. Have used Never Dull metal polish for years to polish all sorts of metal, chrome, stainless, brass, copper, aluminum and projects like cars, gun parts, whatever, very good product. Cleans and polishes just about any finished metal have used it on. (Do not use on lacquered products.) Comes in a metal tin with chemically treated wadding inside. Simply tear off a chunk or wad and rub the metal lightly. Leaves a thin protective film behind. Unless metal's really tarnished badly goes pretty quick. Even then, not bad results. Have always tested on an inconspicuous or hidden area 1st, but haven't had and bad outcomes yet. Soap and water clean up. Have found it in many places like local auto parts, general purpose and hardware stores. A little seems to go a long way.
