Pam,

    Active ingredinet in Attack is methylene chloride, a very powerful
    organic solvent and strong carcinogen. It's also the active
    ingredient in pant stripper, which is often cheaper, by the way. I
    use it on a daily basis, but it WILL remove filling, oiling, waxes,
    dyes, etc from almost anything including turquoise. Most turquoise
    has been treated, otherwise it is too chalky to cut. Lots of material
    is not even turquoise, but a related mineral dyed to look like
    turquoise. 

    For a start on what to do:

    Also Google the Zachary process, they may be able to help. I'd
    suggest you just replace the piece, less hassle. 

Wayne
