    Found some old 35m negatives but they are stuck together.
    I have them soaking in water at moment but doesn't seem to be separating
    them. Don't want to pull apart as it might damage them.
    Any tips, ideas to separate.
    Cheers

    Kodak Photo-flo solution or similar would be better. The darkroom crowd
    here should have some good advice.

  3. That (Photo-Flo) might help, couldn't hurt, but really the only thing
    that's going to separate them eventually is soaking them until they let
    go of their own accord. Don't try pulling them apart if they still seem
    stuck! Just keep them soaking, and don't worry about keeping them wet
    for days if that's what it takes; the emulsion isn't going to float off
    of the base.

    Er, I don't think dish detergent is a good idea. Cleaning detergents
    often contain pH modifiers to make the solution more alkaline, and I
    wouldn't risk that upsetting the dyes in the emulsion.

    Photoflo and other photographic detergents are pH adjusted to be
    neutral, a pH of 5.5 more or less.

    Thanks for all your tips, hints etc...
    They finally separated with gentle pressure.
    Problem now is that one side of each negative is sticky.
    Should I give them a dunk in some soapy water to neutralise?
    Cheers,

    Soaps do this too (in general).

  7. Yes, the emulsion side is a little sticky when saturated. Whatever you
    do, don't put your finger(print)s on it or try to wipe it or such like
    at this point. Hang them up to dry in a place where they won't be
    disturbed.

    It's not a bad idea to briefly rinse with distilled water or shaking as
    much water off as you can without disturbing the emulsion ... or use the
    stuff the others mentioned (I'm not familiar with that product). That
    avoids rings forming from drying drops of water. Once nicely dried, the
    emulsion will harden and not be sticky any more.

    -P.
