Remove the tarnish and discoloration from your copper cookware with Copperbrill, a copper cleaner formulated by Mauviel (a company who knows something about copper!). And it's so easy to use. Apply the paste evenly with the sponge applicator to the outside copper surface of your cookware. Rub until the tarnish disappears. Immediately rinse in hot water and polish to a shine. Copperbrill is available in a 5 oz. container. Applicator sponge is included.
