Have any of you ever tried this stuff?
If you haven't, TRY IT!!! (Kinda expensive though)
I never knew how much copper fouling got left behing after using Hoppes for years.
Run a soaked pad through the barrel and the pad comes out completely blue from copper fouling. It works GREAT. It picks up all the left over copper fouling that other solvents won't clean out.
Be careful though, this stuff might harm you polycoat finish. I don't know how it will affect the finish, but I put all of the polycoated parts aside while I cleaned the barrel. Just in case.
