[SaF] silk screen paint removal

[PeaceNsolace]

I have an unusual question.

I have a unwashed silk screened t-shirt on which the "ink" has begun to peel 
and flake.  That's no problem for me, except I would love to know a way to 
help the peeling along more quickly. The portion that has begun to peel is 
not a desired design anyway, but the tshirt has a tie dye design that I wish 
to preserve as much as possible. With what chemical would I be able to remove 
the remaining "ink" yet keep the dye that IS desired?
