When I clean my pistols, I apply Hoppes #9 to soften up the residue. Then I scrub it all with a toothbrush. A lot of it drips or falls into the cracks and area that I can't reach with a Q-tip. I don't want to leave that all there because then all I did was move the residue from one area to another. I prefer to rinse it all out before it dries and hardens again. I've used WD-40, Brake Parts Cleaner, Carburetor Cleaner and Simple Green.
What do you use, if any?
