I cleaned my triumph anally last night. Foaming bore cleaner. Wire brush, more bore cleaner, wire brush more bore cleaner patch, patch. Then i looked it over ran some windex down to get a nice shine and see what it look liked. Still alittle dirty more bore cleaner, patches, windex, patch. Looks good so i ran some alchole down it. Looked good and let it dry ran some oil down it. The alchole and oil ran down and came out clean and i mean spottless. SO i put it up and left it. When i got home from school i was looking it over and checking it out. I love that gun by the way. I noticed what looked to be copper or plastic fouling. Looks like little bits of grit or copper. Not sure if it is or not. I am going to go shooting first thing in the morning. Is it ok to leave it or should i run a dry or alcholo patch and see whats in it. Then reclean it if it is copper or powder. Not sure how it could since the alchol and oil came back clean. It was sitting by my walk barrel up could it just be some dust. If it is copper or powder could it have damaged the barrel in a day.
