i think i found the proper scrubber now so going to get that rigged back up and try again. I did use CLR though maybe not enough. The bottle i tried wasnt anything special so no big damage or lossDid you use the CLR? I never was able to scratch a bottle. I think you may have bought a cheaper copper scrubby. Use a magnet to see if it is just copper coated steel. That may be. Can you get a picture of it? If so please post. Sorry for the confusion. You can get copper wool From fine to coarse online it is not cheap. Even copper bb's are steel inside and copper coated. Hope it was not valuable.
