I may be late to the game on this 'discovery' but I am with it now.
Just tried one of those cheap (2 for $10) electric tooth brushes you buy at the grocery store on a pistol.
It seems to really help clean the gunk off, better than a regular toothbrush.
Makes it easy to get into some of those hard to reach places around the firing pin on the slide. Got the little bits of stuff off the area between a 10/22 barrel and the frame as well. That normally takes me a few q-tips and a sharp peg to accomplish. Going to try it on an AR barrel extension after the next range trip.
