I have a pan brush but seldom use it. Around here, there is just enough humidity to cause the pan to get moist crud in it between shots. I found that a rag does a better job than a brush. I keep a small rag about 3/4 the size of a shop rag in my bag. It is handy for wiping my hands and the pan. A rag is just an extremely handy thing to keep on hand when shooting a muzzleloader. If I didn't have the rag, I'd be wiping my hands on my pants and then on the way home, the stink from the burned black powder would get on my car seats. It makes my wife complain. After 50 years of marriage, you just learn that if your wife isn't complaining about something stupid that you did, life is just nicer. So, a rag is part of my standard gear.
