hello everyone, purchased a parkerized .45/1911 springfield from friend of mine that was in a plastic carrying case. he had evidently spilled coffee on and in case a few days prior to bringing it to me. got home,opened case and wa-la, i now own a parkerized/coffee finished .45. any suggestions on removing stains. have tried several diff. cleaners with no avail. on the lighter side it fires great and looks rather unique(kinda parkerize/camo if you will)thanks in advance for suggestions
