Benzotriazole Removal

Ted recently recommended someone use benzotriazole as a corrosion inhibitor for copper. It does work well. I would like to know if anyone has had success in cleaning copper that has been treated with triazole based inhibitors and what that process might be?

Hi, Kurt. My recollection from vinyl record days is that manufacturers were able to clean benzotriazole treated copper masters with simply isopropyl alcohol ⇦ on eBay or Amazon [affil link] and a tampico brush. But memories are faulty things :-)
