Wil,
I use Hoppes and brass bore brushes. I apply it liberally, run the brush or BoreSnake, then repeat it for the next two or three days, depending on how much gunk was present. I've soaked parts in acetone for a few minutes, then brushed with a bore brush or toothbrush and that has worked well. Be careful not to get any chemicals or solvents on the grips. Brass wool also works very well to clean carbon and fouling from parts. Don't use steel wool! I cleaned some very cruddy shotgun choke tubes with brass wool dipped into acetone or mineral spirits. I use Rig grease, very lightly applied to the parts when I'm done.
