Lucas Oil Extreme Duty Bore Solvent in the 4 oz size (brand part no. 10907) is a premium blend of cleaning solvents and corrosion inhibitors built to cut through the toughest fouling. It easily removes carbon and powder residue from actions as well as copper and lead fouling from cylinders and barrels. The solvent-based formula cleans deep enough to strip out old oils and grease, then leaves behind a micro-thin layer of rust and corrosion inhibitor on metal surfaces and bores. It’s safe on polymers and factory-applied firearm finishes.
