[QUOTE="dok7mm, post: 1560215, member: 90080"] If you are referencing normal carbon residue, BoreTech C-4 is the best I have ever used. For hard, baked on carbon from high burn temperature powders, it is a much different situation. If the layer is relatively thin, I've been able to remove it with Ed's Red formula (available from Brownells), scrubbing with bronze brushes and monitoring with a borescope. For really hard, caked on situations, it takes soaking with C-4 + bronze brushing + IOSSO or JB abrasive pastes along with checking conditions with a borescope. For the record, I have tried using CLR on bad deposits and found it was no better than C-4 at softening the carbon. [/QUOTE]
