After much thinking for an old brain, I remember that we used something like this (sometimes instead of Brasso) to clean the brass for our uniforms. I guess that begs the question if whether anyone has tried Brasso for cleaning copper clad? I know it gets brass down to the bare metal pretty quickly. As I remember, so does the stuff like this we used to use, but I thinks the stuff on the pads left more of a film than the brasso, but was _much_ easier to use. Brasso required a little elbow grease, and this stuff just stripped the tarnish away, but like I said, left more of a film. Of course, this is 20+ year old data, scrounged out after 20 years from a less than reliable source (my brain, or what passes for it these days). Richard
