A safe and quick way to clean your bore. Based on their 725 gun cleaner, the Slip 2000 Foaming Bore Cleaner will effectively contact all surfaces of the bore and break down any powder residue and carbon buildup.Simply spray into your bore through the breech, wait about 15 minutes, and push the cleaner out with a patch, mop, or just rinse it out. As with any good cleaner, be sure to re-treat all metal parts with a Slip 2000 lubricant after cleaning to protect the metal from rusting and corrosion.
