no chrome has come off yet from the lye

Well after two months. In the end Ammonia does get off the copper if you have all the time in the world. Like I said earlier, it gets the flat big areas fast (Couple of weeks). I’m taking this to the next scientific level. I’m going to surf the web for a young scientific forum and find me some geeks to collaborate with. In the air of things in the world right now. Don’t be surprised if I come back and tell ya copper plating is the reason for global warming. Bob L

Exeric: Ferric Chloride will remove nickel plating. I buy it a Fry's electronics, as folks use it for etching circuit boards. I have never tried it on copper, but I'll go throw a chunk in just to see.
