The Museum Precious Metals Cleaning Plate

Using electrolytic action instead of traditional chemical-polish abrasion, this tarnish remover bathes away tarnish from oxidized silver without removing any of the underlying metal. Simply place the 6" x 8" cleaning plate in a non-porcelain sink of hot water, add the activator, and immerse the tarnished metal. Tarnish dissolves and transfers to the cleaning plate, which lasts indefinitely and rinses clean under the tap. Non-toxic and harmless to precious gems, the tarnish remover cleans copper, quality brass, bronze, stainless steel, silver, and gold (but each type of metal must be cleaned seperately, do not clean different metals in the same wash). Includes 1 lb. of activator; use 1 tbsp. per 1 quart of water. Not for use with porcelain sinks. 6" W x 8" L. (3 oz.)
