Can anyone recommend a good copper fouling remover that lets you know when your barrel is free of copper. I have been using Barnes CR 10 but want to get away from the ammonia, in the winter it makes it tough to clean my guns because I need to keep my garage door open to keep from inhaling the amonia and it can get cold even in the day time. I tried Hopppes elite and MP Pro but they are gummy and sticky and leave residue in the chamber and the patches never came out clean even after repeating the process several times. At least the Barnes let you know when the barrel was copper free when the patches showed no blue color.
