    If the chains were touching then that is all it takes, spring steel
    touching 14k clasp/chain touching 18k chain will do it. However
    there is spring material in a typical bayonet clasp.

    Pickle even used a couple of times will have enough copper ions in
    solution to plate out.

    Don't leave it in there too long as it will eat the spring
    mechanisms in the clasps
