Carbon Killer removes carbon on contact. Use in chambers and barrels as a bore cleaner. Apply to cylinder faces, bolt faces and any other hard to clean areas and allow to soak for 2 to 10 minutes. Carbon, lead, copper, plastic and burnt powder will wipe clean with a nylon brush. Next cleaning will be much easier if used with a Slip 2000 Lubricant. Users will actually be able to wipe carbon and plastic wad fouling away.
