    Hello Janet, I was still young, but it really happened. He put jam
    on the thing and started to heat till till the piece smoked and was
    all black from the burned carbon. Then he threw it in a pickle, took
    it out, cleaned it a bit, and the piece was clean. I have been
    thinking about this the last couple of days and considered the
    possibility that he played a trick on me - maybe he just did
    something crazy in order to make a kid laugh. I don't think that his
    pickle solution was Sparex ... However, yesterday we had a party
    going on here and since everyone was chatting for hours about
    fascinating stuff such as the colors of the curtains for a new house
    on which we haven't decided yet, I escaped to my room, took a piece
    of sterling silver sheet and a selflocking tweezer from steel and
    contaminated the thing in old pickle. After that I put strawberry jam
    - the first thing I could find - on it and to heated the piece till
    it smoked and was black. I then 'quenched' it in a new (and I have to
    say strong) pickle solution (the usual Sparex but more than usual):
    go over it with a cloth and the silver is clean. Just try it out for
    yourself. It gave me a good feeling. I don't know what my family in
    law thinks about it. I am not a chemist, but I suspect that it
    doesn't have to do with citric acid or anything like that. It is as
    if the layer of  contamination somehow reacts with the carbon, which
    seems to suck it up or something. I might be totally 
    wrong on this. Best, Will
