    Cleaning old/dirty negatives.

    Just received an envelope containing 6 old negs. from the 1930's.Talk about rough shape.Stains,finger prints & dirt.
    Read some of the posts dealing with this issue that suggest either:1.Bath in pure isopropyl alcohol 2.A mix of I.A and photo flow.
    Has anyone done this with old negs.?

    It depends a lot how bad they are.
    Sometimes cleaning with PEC 12 Photographic Emulsion Cleaner is all that is needed.
    Re-washing should work, but with old nitrate negatives there's a chance of the emulsion coming away from the base.

    If the negs were not well fixed originally then re-fixing and re-washing is an option.

    I have had good results in cleaning old negs using a C41 formaldehyde based stabiliser bath.
