A couple of years ago I bought the most amazing set of modernist jewelry. There were some crazy acrylic brooches and a ring (which are impossible to take pictures of) , and this very nice brutalist copper necklace. So here comes the terrible part of my story: At the time I had little or no knowledge about cleaning things (I still am clueless about cleaning the house and I just stopped cleaning jewelry, that works great). Anyway, I think I might have tried to clean this nice necklace with lemon acid or vinegar.
Immediately the whole thing turned green and grey and it has the most terrible 'rash' (rash is for baby's, but I dont know the correct word for jewelry rash in English).
Since last time I cleaned my necklace and in the last two pictures you see the result. Almost all green has gone. I m happy with the result, though next time I will definatly try the ketchup method.
And so here is my question: does anyone have an idea about the maker?
Thank you so much!

    Sorry, I don't know how to reverse back to pre cleaning. I have damaged a few things myself :(

    Wow! This is so cool. First off you can use a toothbrush or a soft wire brush to take the verdigris off. I have had the SAME thing happen when I cleaned some of my metals. Art8jason gave me some tips. I'll see if I still have his postings and get back to you.

    No - my friend Ar8jason once removed also any advice removed...

    I haven't tried this - looks like it has same ingredients that you tried.

    Yep,I use it on brass and you can dip your FrenchFries in it at the same time!

    Thanks roycroftbooksfromme and gargoylecollector for your tips!
    After googling ketchup and copper I figured out vinegar would do the trick as well, so I took a pan, boiled some water with 1 spoon salt and 1 spoon vinegar and dropped my necklace in the boiling water. I left it in there for a while, and tata! It really cleaned up well! I cleaned it with a soft cloth afterwards and its very shiny and new now. The only small issue I have with this method, is that all parts look like copper now, while before it had some white metal too. But thats just a small issue in comparison to how it looked before.
    I m really happy! Thanks a lot! I will try to post a pic of how it now looks.

    the reason she likes ketchup, you have more control over the out come leaving some on to keep its look ...

    I added pictures with the result of my cleaning. The pics are not great but I think you can definatly see the improvement.
