Sorry that should say Carb/Brake CLEANER. I'll try not to rehash,.and hopefully this wont get into lubrication. For many of years I have cleaned with Remoil or something similar such as browning gun oil in an aersol which almost flash dries. I like the power blast to get down in the trigger assemblies ect. and let the crud drip out. Not just for Glocks. I have Ruger Marks, Marlin 60's. Smith metal pistols, ect that I only field strip when cleaning. Then I lightly lube with whatever, eexzox, clp, mobil, whatever. Oil is oil. But that is another topic. Lately, I have been wanting to leave as little residue as possible before lubing and have been reading thread after thread on Brake cleaner. Usually they dissolve into a heated debate on Mobil one for some reason. LOL. I read about hexane, and Toulene, and gun scubber versus brake cleaner. What I want is a specific answer if anyone knows. HAS ANYONE EVER SUFFERED ANY DAMAGE DUE TO BRAKE OR CARB CLEANER ON THEIR GUN. Either to the stainless, the polymer, the nylon, anywhere on their guns internals or finish?? Also is there any difference in brake cleaner and carb cleaner?? Is one brake cleaner better than the next brand?
