[QUOTE="Greyfox, post: 1447023, member: 10291"] Having used Sweets for years, I switched over to the chelating solvents like the BoreTech Eliminator, and for more stubborn build up, the BoreTech Cu+2 and Proshot copper solvents. IMO, they work as fast, if not faster, and are harmless to stainless and CM steels. Ammonia WILL etch steel if exposed for long periods(as will peroxide). One thing to keep in mind when observing copper when cleaning. It may not be the barrel that is stripping copper, but the copper residue from the gas normally formed by the bullet traving down the barrel that is settling out. How many times have we seen the patch turn blue when cleaning the ports/interior of the muzzle break with a copper solvent. There is no bullet contact, but it’s still there. [/QUOTE]
