    Hi Marc, You might want to give Bill Seeley's Hydrogen Peroxide
    pickle a shot. Quoted from his article, "The following procedures and
    formulas provide for the removal of red scale from copper, brass,
    bronze, nickel silver, reticulation silver and some gold alloys. It
    will remove the copper coating from silver that has been accidentally
    pickled in an iron contaminated acid." 

    Here's the article and recipe from the ArtMetal Web site... can also
    probably be found in the Orchid archives:
