of activator; use 1 tbsp.
per 1 quart of water. 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). Simply place the 6 x 8 cleaning plate in a non-porcelain sink of hot water, add the activator, and immerse the tarnished metal.
