I'm having a perplexing problem with what appears to be dye staining on
Teflon laminate.

The laminate is 6010 LM Teflon.  The stain occurs in the developer, on
exposed Teflon areas.  Running the material through a fresh developer
solution eliminates the staining; the problem is I have a number of parts
that are already stained and I need to remove it.  I've tried various
cleaners, solvents, and of course, stripper solution.  Nothing seems to
affect the stain.

Anyone have any suggestions that will help me remove this stain?

Thanks.
