Flitz Tumbler/Media Additive is a strong cleaning solution for demanding metal cleaning chores. The liquid solution in the 16 oz. container is eco-friendly and suitable for use on any metal, including brass, copper, and others, without deadening the primer or stressing the brass. The product may be used with corn cob, walnut, or other media, cutting cleaning time in half as compared to using plain media alone. Flitz Tumbler/Media Additive cleans, polishes, and protects brass and nickel without depositing or harming the metal or priming.
