What I am saying is that after you use bleach AND rinse off the
bleach, then still use a little vinegar (or something) to neutralize
the remaining few base ions which will cause the color in Dr. Martins
or other dyes to disappear before your eyes when applied especially
certain colors. I am not saying to directly mix bleach which is a
base with vinegar which is an acid. No amount of water rinsing
(practically speaking) will totally neutralize the base (bleach) on
the film surface and remaining emulsion and this slight residue of
bleach will ruin color intensity. I have used the technique with no
ill effects, but still have the work space should be ventilated.
I have also applied this technique when working outside with longer
strips of film. After rinsing the bleached strips in a bucket of
flowing water, I then add a little acid (vinegar) to the semi-final
rinse. One final water rinse and then dry.
