I'm a bit of a clean freak too, but I don't try to remove the carbon after every range trip. When it's time I normally remove the cylinder and put it in a small jar full of a solvant (ed's red or hoppes) and let it soak for a week or two. It won't get everything, but it does tend to loosen it up so a bore bush can take it out.
For SS guns, I use a lead remover cloth that does a dandy job on carbon, with very little effort. Not usable on blued guns, though, as it removes the bluing.
