    That said I would still try a rewash---don't have anything to lose
    I agree. It cannot hurt. I might do the entire fix, wash and photo flo thing.

    Do you always use photo flo at the end of your processing?

    The color stabilzer also contains photo flo.

    I never use any rinse after the fix step for B&W or color, just wash and then use either photo flo (B&W) or Stabilzer (color).

    Here's what I do. Please tell me if it's wrong. Soak in water briefly, develop, stop with water, fix, rinse 1 minute with water, agitate lightly 2 min. in hypo clearing agent (to reduce rinse time), rinse 6+ minutes with water, final rinse in distilled water. (I guess I'll try adding photo flo to the process and see if I can see a difference.) I used to have a chalky-ish residue till I started doing a final rinse in distilled water. We have well water.

    Janet;

    What you are doing seems fine. Photo Flo is like taking out extra insurance.

    You do this:
    Pre-wet, develop, stop, fix, rinse, hca, wash, rinse.

    I do this:
    Develop, fix, wash, rinse.

    Developer: very dilute, one-shot.
    Fixer: very dilute, one-shot.
    Wash: 5-10-20 sequence.
    Rinse: Photo-Flo.
    Room temperature distilled water ALL solutions.
    I've also hard well water.

    An eight blade film squeegee is employed;
    makes for quick drying.

    A quick look; perhaps a light leak? Dan

    Yes, no light leak. What format, 35mm? A big drop
    trailing down. What ever, it REDUCES density in
    the negative. Dan

    No, 120.

    Dan, what does "5-10-20 (wash) sequence" mean? And what developer and fixer do you use? Just curious because you said, "very dilute".

    I'm seeing such weaker density spots on my 35mm negs now and then. Lower left corner in the attached image. It is a scan from a straight print.

    The spots are usually evident only in larger areas of uniform density, such as overcast skies. They look just like minute drops of water left on the negative after wiping. As they appear only on sloppily washed negs, I've imagined that the stain might be caused by some chemical trace (fixer?) left on the emulsion surface to "eat" some image silver during drying.

    I dry my films in the darkroom, where humidity is high and temperature low (during the night). Even in the summertime it takes well overnight until the negs are completely dry.
