After going on a prairie dog shoot and running through 500 rounds of Fiocchi's finest .223/50 gr V-max, my TBAC CB brake/mount had quite a respectable coating of carbon on it. After poking at it with Ream-N-Klean pipe cleaners and KG1 carbon dissolver for about 30 minutes, I decided to try to live better through chemistry... and soaked the brake in Piston Kleen (http://www.orisonmarketing.com/pistonkleen.html) for about 90 minutes.
I was REALLY impressed with the results... the KG1 was doing a respectable job, but the Piston Kleen resulted in me being able to flake fairly sizeable chunks of carbon off the brake. I flaked off what I could with another Ream-N-Kleen, and dropped it back in for another soak for an additional hour or so. Once more with the Ream-N-Klean, and the brake was completely clean. There's a touch of pitting on the first baffle of the brake, but other than that it looks as new.
I said all of that to say this... if you're as anal as I am about cleaning your guns (if you're going to take the time to clean it, get it clean), you may want to invest in some Piston Kleen to address those parts with particularly heavy/stubborn carbon build-up.
