Due to overwhelming demand, this improved Butch's Black Powder Bore Shine does it all just like the original, but now it's been specially formulated to clean better, faster and leave a mirror-like finish to any firearm or black powder rifle. This powerful solution delivers a benchrest level of cleanliness and easily removes stubborn powder residue, breaks up lead and plastic fouling, and neutralizes corrosive black powder acids. This odorless bore cleaner is non-toxic, non-flammable, and biodegradable. It's safe enough to use on all plain and finished metals, aluminum, polymer stocks, rubber, and most plastics. Available in an 11 oz. flip top bottle.
