    I hang my 35mm & 2 1/4 negs to dry in my small bathroom, with the door
    closed. I am plagued by dust marks that show up on 8x10 and 11x14
    Does anyone have a remedy for this?
    Has anyone tried spraying the room with a fine water mist before
    hanging? Would the room dust be carried by the droplets as they sank
    to the floor?
    Any help would be appreciated.

    Is it dust or sediment in the water? In my first darkroom in this town, I
    had terrible problems with "grit" on the negs. I installed a faucet water
    filter, and the problem went away. When I built my second darkroom, I
    installed a "whole house" type water filter on the incoming water supply. (I
    change the filter every three months)

    Others here have suggested running the shower to steam up the bathroom
    before hanging film/prints to dry. The premise is that it settles dust and
    causes the film/prints to dry more slowly (and flatter).

    It should go without stating that one should use a final rinse of distilled
    water ($0.75 per gallon) mixed with a little Kodak Photo-Flo (or
    equivalent). Use only a few drops of Photo-Flo and not the ridiculous amount
    suggested by Kodak. Get a medicine dropper at a drug or discount store.
    Discard the final rinse solution after each session.
