Premium Bore Solvent SPEC1 Premium Bore Solvent will dissolve the most tenacious carbon and lead on contact. For barrel cleaning, push a wet patch or mop through the barrel and allow to soak for 2-5 minutes. Repeat if necessary. Light brushing may be required. Wipe or rinse clean. Follow with some SPEC1 Premium Blend lubricant on a patch or mop to displace any moisture. For larger parts submerge completely in solution. Allow parts to soak for 5-15 minutes. This process will vary with the frequency of cleaning. Remove and wipe, brush, or rinse clean with hot water. SPEC1 Premium Bore Solvent can be used on ALL Firearms.
