Butch's Black Powder Bore Shine comes from a special cleaning solvent used by the U.S. Military. This Black Powder bore cleaner, like the original Bore Shine, does it all. It removes powder, lead and plastic fouling from your Black Powder rifle faster than any other bore cleaner. It is odorless, non-toxic, non-flammable, biodegradable and protects against rust and corrosion. Safe on all metals.
