Since I can't post websites here, I at least brought this quote out of many sites that found Sea Foam perfect for cleaning guns!
"Well, I tried Sea Foam on some stubborn carbon build up around the bottom side of the bolt as well as the chromed inside of the bolt carrier. Sea Foam wiped away that stubborn carbon like it was just spilled milk!!!
I dabbed a rag into some Sea Foam and then covered the carbon to let it soak on the parts. I then proceeded to clean the other components of the gun. About 10 minutes total, I went back to the Sea Foam saturated parts and was amazed how easy the carbon residue came off.
Ive tried them all.... Hoppe's #9, Tetra, Flitz, Brownells "Ed's Red," J-B, etc.... Name it and I've tried it. The Sea Foam seemed to work best.
I did NOT apply a small amount on the plastics, nor have I tested it on fine rifle wood stocks (yet). That's next. I probably will use this now for stainless, bores and the internal gas tubed weapons (AR's and AK's) that get really dirty. I'm betting that it will clean up the nasty fouling of .22 rimfires at the chambers of my stainless 10/22's.
Anyone else try it on guns????"
