After hearing rave reviews about Wipe Out foaming bore cleaner, I decided to try it out. I have an old Tokarev SVT rifle with layers of copper fouling in the barrel, perfect candidate for testing this stuff on. I filled the bore with the Wipe Out foam, let it soak for 4 hours, then patched it out. What came out of the bore was an amazing amount of blue-colored crud--the copper fouling had been liquified. This is much better than I expected, most copper solvents remove very little of the fouling. Even Sweets and Barnes CR-10 couldn't touch this stuff. I had used them previously on this same rifle.
The only thing I didn't like about Wipe Out is that it will remove the finish on wood stocks unless you get it off quickly.
