Hard carbon fouling has always been a difficult cleaning problem, usually involving abrasive cleaners and lots of short-stroking the bore or throat area. Carb-Out is a very strong, carbon specific solvent which easily removes hard carbon deposits. Carb-out can also be swabbed through the barrel between relays or shot strings to lessen carbon foulding. Leaves a thin, sub micron rust preventative coating on barrel steel. Flammable Liquid. Available in an 8 oz. screw top can.
