IMO...There are very few problems in life that can't be solved with the judicious application of 4227 or 4198. Like you, and contrary to Shrapnel and Venturino's view, no disrespect intended, I have a personal abhorrence for scorched hard carbon particles in the bore of my 150 yr old rifles. Baked carbon particles do not do engine cylinder walls any good, but maybe they are good for rifles.
