This is an all-in-one cleaner, lubricant, and preservative. By applying this solvent to your firearm, you are creating a thin fildm which stops rust and corrosion for long=lasting protection. It penetrates into tight fitting areas for easy dis-assembly of parts, and seals out moisture with a thin film lubricant reducing surface friction. As a cleaner, the 085 solvent removes carbon, gun powder, dirt and grime from metal surfaces.
