    What is a good way to clean/wash processed color negative film strips
    as a prep to scanning the film? I was thinking of bathing the film
    strips in a dish of "Rexon Anti-Static Film Cleaner" and lightly
    rubbing them with a soft sponge. Then, squee-geeing them dry before
    inserting them into the film scanner. Any dangers to this? Any better
    recommendations?

    I don't want to spend too much time on the cleaning (the scanning
    takes long enough). The object is to remove major stuck-on dirt. The
    scanner user "Digital ICE" technology to remove surface defects.
    However, I like to use it on its lightest setting because using
    Digital ICE can have a softening effect on the image. But, using the
    lightest setting will not remove the worst cases of dirt.

    Thanks in advance for your suggestions.

    A word about using the Edwal cleaner. After ruining several negatives, I
    have found that the best way to use it is with cotton, not acrylic q-tips.
    Wet one end in the cleaner, then shake it almost dry and run it gently, in
    even strokes over the emulsion side of the negative. Use gentle strokes,
    then follow with gentle strokes of the other dry end of the q-tip to dry it
    and keep from streaking. Streaking is the worst problem with this cleaner,
    and can show up more readily on a scan than it will through an enlarger.
    Follow up with the same treatment on the non emulsion side if needed.

    Frankly, unless there are dirt marks on the film, I would do nothing other
    than dust it, using canned air, then maybe using an orange cloth to prevent
    the static electricity from attracting more dust.

    I trust that the scanner has been cleaned also?

    Solvents are a bad idea for all but the worst embedded dirt. I like a
    polyurethane mat and roller using the same particle transfer technology
    used to clean motion picture film The company I bought from originally
    seems to be gone, but you can see similar products at
    http://www.fortex.co.uk/products/page-cleaning-rollers.html. The rollers
    and mat should be cleaned regularly.

    For resistant spots, I use PEC-12 and PEC-wipes.
