These are some results of the etched copper fabric. After 24 hours in a balsamic vinegar and salt solution it didn’t look like anything was happening. Another 24 hours later, the exposed copper was coming off quite well. We think it took so long because of the new “tarnish-resistant coating” on the fabric, but we got quite good results in the end.
