When I am finished shooting a revolver I spray it down with WD-40 to loosen the carbon. Then I wipe away the carbon gunk with a rag and, if necessary, clean the cylinder chambers and bore with something like Butches. Then I clean with Breakfree CLP. I go over the outside of the revolver with a short stiff brush (like a stencil brush sold at Walmart and Hobby Lobby) which has been soaked in Breakfree. This gets down into all the nooks and crannies. I let it set overnight and then gently wipe the excess Breakfree off. I buy Breakfree CLP by the gallon. On the rails of my autos and my rifle bolts I use a little Tetra grease.
