The problem is that to clean a ML properly (completely) you have to partially dismantle it, and that is what takes the time! I can clean a barrel very quickly using two quarts of boiling water,four or five clean, dry patches, plus a cleaning rod with a jag tip. But I have to either remove the barrel from the stock, and/or take out the nipple (or breechplug, on an inline) before pouring the water throughthe bore. Taking nipples out, or removing breechplugs, cleaning up the small parts, then oiling and reassembling all the parts is what makes it a time-consuming exercise, not just getting the fouling out of the bore. It takes me about half an hour to completely clean up one sidelock rifle, either flint or percussion. Maybe a little less time for an inline.
