   14 years without a splash! You must be a very careful
   worker! You have two choices:
   something mildly acidic (e.g. 5% acetic acid) or, if it's
   on white fabric, bleach. Toluidine blue has little affinity
   for cotton, and would probably come out with a few washes
   anyway. You're lucky it's not alcian blue, which is very
   permanent.
