Flitz Tumbler Media Additive

Removes oxidation, tarnish, lead buildup, fingerprints, and other contaminants to leave brass, nickel, and just about any metal bright and shiny. Combine with corn cob, walnut shells, or other media to cut tumbling time in half compared to using media alone. Ecologically safe and contains no ammonia, so it won't damage primers or make brass brittle (no ammonia smell, either).
