Originally created for military use, Ballistol has been used extensively in Europe for over ninety years to keep firearms clean and free of troublesome lead, copper, and powder residue. Cleans & dissolves traces of copper, lead, brass, and zinc. Lubricates and protects firearms, stocks, and barrels by leaving a film that protects against rust and corrosion that won't gum-up or harden over time. Works well on tough powder residue and emulsifies with water. Mildly alkaline, Ballistol neutralizes the acids that eat away the insides of barrels. Contains no carcinogens and since it's bio-degradable, you can be sure that you won't have to fight a bad smell and toxicity.
