Just bought a new ATI 1911 and it came from the factory with a fair amount of cosmoline in it. This is the same practice that Armscor uses on the Rock Island 1911s. My question is, is mineral spirits really the best way to get it off? Will it cause damage to the bluing on the gun? Does anyone here have any other methods? I'm assuming that just cleaning it with CLP won't get it all off the gun.
