My 2 cents worth -
if you have been using Kodak stop bath, and it has shown the colouring that
indicates the bath has been exausted, you may try just adding acid until the
colouring disappears again.

Generally, you want the acetic acid concentration to be in the range
of 2 to 4%, and vinegar is usually 4 to 8% acetic acid, so in an
emergency use pure white vinegar at 1:2. It's not really critical,
except to the longevity of your fixer.
Try not to use balsamic or pepper infused vinegar :-).
