Hoppes No. 9 Foaming Bore Cleaner 12 oz Spray Bottle

The Hoppe's No. 9 Foaming Bore Cleaner takes the work out of clearing a fouled bore. Packaged in a 12 oz spray bottle with an easy-dispense applicator, this foam-style solvent is formulated to dissolve and lift stubborn copper and powder residue from firearm bores without brushing or other mechanical cleaning.

The orange foam serves as a built-in effectiveness indicator: as the formula works, the foam turns blue where it is pulling copper out of the bore, and turns black where it is breaking down powder fouling, so you can see the cleaning action happening in real time. The thick foam clings to the bore wall, allowing the solvent to dwell and penetrate deposits deep in the rifling.

Suitable for routine maintenance on rifles, shotguns, and handguns, the No. 9 foaming cleaner is a fast, low-mess option between more thorough solvent-and-brush sessions. Each bottle contains 12 oz of bore cleaner.
