Elaine,

    After you have finished the etching off the copper from the silver,
    rinse  the metal very well under running water to remove all the
    ferric chloride. Be sure to wear gloves when handling chemicals.
    Place the cleaned, washed piece of metal in a bath of household
    ammonia. I use lemon  scented without diluting it at all. I place the
    ammonia in a covered  plastic container so the fumes will be
    contained; it must be deep enough to  cover the metal entirely plus
    about 1/2 inch. Be sure to wear rubber gloves and  not inhale the
    fumes. Once this has soaked in this solution for a short while, take
    out of the bath, rinse off under running water and scrub with a green
    or red scrubby. This should remove the black (carbon deposit from 
    the ink) and/or the paper from the metal. You can also use a very
    fine  brass brush to accomplish the removal of the carbon deposit. If
    you are  still having a problem, you can scrub with barkeeps friend,
    a product that is  found in the cleaning section of the supermarket.
    It is a non-chlorine  based mild abrasive. Be sure to rinse well
    under running water between each  application of chemical and/or
    abrasive material so you do not have any  adverse chemical reactions.
    This should get all the black residue off  the metal. Good luck.
