I haven't found anything better than Boretech Eliminator for getting copper and carbon fouling out of old milsurps. There are some I haven't tried that may work just as well, but I can't imagine them being any better.
One good thing about Boretech is it's a preservative. So there's no way you can leave it in the barrel too long.
