Ballitsol Multi-Purpose Tool Oil — 4.0 fl oz Liquid (non-aerosol) CanBallistol can be used to lubricate, penetrate, clean, protect, and preserve tools, firearms, leather, knives, marine equipment, fishing gear, locks, wood, metal, rubber, and so much more.Ballistol is an outstanding penetrating oil, creeps into the finest cracks, and loosens nuts and bolts. It can also be used as a cutting/boring oil.One of the most astonishing features of Ballistol is its versatility. There are other products on the market, but none have the same wide range of applications and capabilities as Ballistol.At the turn of the 20th century, the German Imperial Army began looking for a multipurpose oil that could be used to clean and maintain the metallic parts of a rifle, while also protecting its wooden stock and a soldier’s leather gear. To develop this oil, the Army contracted with Friedrich Klever and his son Dr. Helmut Klever, a professor of chemistry at the Technical University of Karlsruhe. In 1904, Dr. Helmut Klever succeeded in producing the special compound, which he named “Ballistol” (from the words “ballistic” and “oleum”, the Latin word for “oil”). It soon became obvious that this new “ballistic oil” had truly amazing capabilities, and in 1905 the Imperial Army tested and adopted Ballistol, which stayed in use until 1945. By then, however, word had spread and within a decade, hunters, boaters, hikers, and outdoorsmen in Germany, Austria and Switzerland had converted to using this new “miracle oil.”Ballistol is biodegradable, and neither its use nor its disposal will pollute our air or water. Its natural decomposition will not produce byproducts that are harmful to the environment. The aerosol propellant is a propane/butane blend that does not contain CFCs. In addition, Ballistol is non-carcinogenic and skin safe.WARNING: Cancer and Reproductive Harm -www.P65Warnings.ca.gov
