I have 2 custom made flintlocks...I just put a tooth pick in the touch hole, pour some water down the barrel, put my thumb over the muzzle and tilt it back and forth, pour the water out, run a couple of patches down the bore, run a couple of alcohol patches down to help dry the water...Then I run one patch with WD-40 down, followed by a patch oiled with your favorite gun oil and I'm done.
