For my Kibler as well as all my pinned barrel flintlocks for the last few decades I use MAP. Cleaning is fast and thorough with no mess or negative effects. I keep a pint of MAP( Murphy’s Oil Soap 4oz, Peroxide(3%) 6oz, and Alcholhol(70-90%),6oz….In a dark bottle. Plug the flash hole(toothpick), pour a few ounces down the barrel, cover bore with thumb, inverting the rifle a couple of times, let it sit 5 minutes, pour out, wipe dry, final flush with an ounce or two of alcohol, wipe dry, run a patch of WD 40 or Ballistol down the bore, Wipe down the lock/barrel with any black powder solvent, lube surfaces, done.
