i clean the bores, nipples and breech plugs of my muzzleloaders with Windex with vinegar, now called Windex Multi-Purpose Cleaner. The stuff contains about three percent acetic acid.

Windex with vinegar neutralizes and dissolves the crud left from firing blackpowder, 777, Pyrodex and the APP made powders. The crud is alkaline in nature.

i swab at the range using Windex with vinegar. Before leaving the range the bore is swabbed with a patch wet with Windex with vinegar. When i get home the bore is again swabbed with a patch wet with the stuff. This is followed by dry patches. The bore is then swabbed with a patch moist with 3 in 1 oil or Militec 1.

Nothing cleans a breech plug as fast as Windex with vinegar. It dissolves the 777 crud ring too.

Windex with vinegar will not harm your gun. i use the stuff to clean my antique Winchesters after firing blackpowder loads.
