The old "Moose Milk" formula of Murphy's oil soap, Hydrogen Peroxide and alcohol goes back forever in muzzle loading circles and it works well. Some experienced rusting after because they thought the Murphy's was oil. It is not and the bores must be dry and oiled after cleaning. The hot soap and water works quickly and gets results much faster. Tight jag and patches pump the water up into the bores and washes the fouling out quickly. It takes me all of 10 minutes to completely clean my guns. 2 or 3 inches of the muzzles are in the water and when clean dry very quickly. Do not forgo the black powder experience just because you are afraid to clean. It is very easy and a great amount of fun hunting or clay shooting with black.
