I think I can help here...I was the one who recommended the wood
bleach. :-)

Analine dyes are no longer actually analine based...analine was a
highly toxic substance and has long since been removed from what we now
call analine dyes. The name stuck around though. As I understand them
now, they are metallic in nature, some sort of metal salt or something.

I just did a further Google search, and they recommend using the
chlorine-based bleach to remove dye-based stains. (Most said it was
ineffective on pigment-based, however.)

The transfast is all dye and no pigment, so chlorine is probably the
way to go. I agree with the others, though...probably best to first
get as much off with the original solvent as possible.
