I use the Gunslick foaming bore cleaner. It cleans just as well, is easier to find, and has a clear flexible tube you stick in the chamber. Hit the buttom until you see it coming out the muzzle, hold the tube there for a few seconds so all the extra goes out the muzzle instead of back in the chamber. After the first few seconds it stops expanding and you can remove the straw. Make sure the muzzle is pointed slightly down so nothing runs back into the action. Excellent product.
