    Rewashing negatives with water spots?

    So I have a few negs which I washed improperly and now have water and dust spots all over them
    I've also cut them already
    Can I rewash, use photo flo and hang them by their sprocket holes?
    Thanks

    Yes, but be careful as the extra handling can lead to scratches.

    I do that all the time!

    I make a "hanger" with paper clips that goes into the sprocket hole. I make a "weight" that goes to the other end of the film out of the same stuff. The short strip will curl badly as it dries, so without a weight, you'll end up with a coil. I wash them by carefully reeling strips into my developing reels, so the imaging surface doesn't touch anything during the re-washing process.
    Develop, stop, fix.... wait.... where's my film?

    Yes.. like everyone said. sqeegee them with your photo-flo fingers, not the rubber ones. Your sure to scatch them with those.

    It may not be necessary to rewash them if you just have a few water marks. These only tend to form on the shiny side of the film, so lay the strips in turn shiny side up on something clean like a negative page. Then breathe on them as you would to mist up a mirror and then wipe them gently with a lens cleaning cloth. If the spots don't disappear, dab a bit of ethanol on the cloth and wipe again.

    Soak them in distilled water or something similar like demineralised.

    The question needs to be asked, are the water spots ACTUALLY causing any visible issues when enlarging? I get drying marks occasionally and find that indeed that they are on the shiny side only. I have also found that quite often, they don't appear to make too much of an issue when put in the enlarger.

    But, as they say, your mileage may vary...

    On a... ::cough:: flatbed ::cough::
    I can see the spots as weirdly colored splotches
    This was the first roll of film I processed and I like quite a few of the shots on that roll

    Cough:scanner:cough shows stains, scratches, and water spots far more clearly than an enlarger. I don't know why but it does. I had one like that but printed just fine on my enlarger.

    What I usually do is to soak my film in weak acid (like stop bath) to losen the calcium content of the stain, then soak long time in filtere/distilled water. Then rinse, photoflo, and dry. It usually works.

    I wouldn't scrub it with alcohol as you have a chance of scratching the film. Even if it is on back side of film, it can show. I've done it.

    I have recently tried a different rinse formula that I have found in APUG. To prevent future rinsing problems I would recommend that.
    1 oz ilfotol/foto-flo mixed with 7 oz isopropyl alcohol, becomes the stock solution.
    Use it diluted 1+25 or 1+24. It works better than plain foto-flo imo. I used bottled water for final rinse and no problems spotted in cough:scanner:cough.
