Correction: Help - film drying dust

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
prints.
Does anyone have a remedy (short of spotting) 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.

I used to get the occasional dust while hanging to dry on both 120 roll
film and 2.25x3.25" sheet film. Then I built a drying cabinet from 1"x8"
lumber. There's a 50 cfm fan on the bottom pulling air out, a piece of 1"
open-cell foam on the top as a filter and weatherstripping on the door edges
so airflow is in on the top and out the bottom. I've had no dust on
negatives since I started using my box.

Your design may be simpler.

Around 20 to 30 minutes before hanging the film out, carefully wet the
walls and the floor of the bath with tap water, and then close de
door/s and eventually the window/s of the bathroom. You will create an
ambient satrurated of humidity wich "capture" the dust. When processed
the film, inmmerse it in Photo-flo (1:400 filtered water) and proceed
as usual. Hang the film out in the bathroom. You will get no dust at
all from the air. But you may get dust and other particles from
another source i.e. the processing water and the photochemicals
itself. If so, you need to use over the wet film the same procedure I
am making, using a WET, clean dust brush as used in dusting the photo
lenses. Start from top and go to bottom of the hanging film, front
(emulsion side) and rear. With the aid of the dust brush all the
particles will go down to the floor with the water itself. And no
scratches at all. Regards. Eduardo Benavidez

In case you missed my previous recommendation in another thread:

Sharper Image Ionic Breeze "Desktop" model. (Providing you can afford
it). Fits in the smallest of darkrooms.

I have an ion generator I bought on eBay for much less than $250. :-) It
does work. I also have a couple of gadgets for deionizing electronic work
spaces, but I'm not sure what they offer other than cool or warm breezes.

I have a small, 8" deep cabinet with nothing else for drying. the
environment is quite dusty. Prior to that, I used the bathroom. Going
back 30 years never, repeat never a dust spot on a negative. Following
wash 1 minute in standard dilution Photoflo then squeegee and hang.
Once a scratch from some grit on the squeegee, now I use ny index and
middle fingers. As good is one of the many formulas where a little
isopropyl (rubbing)alcohol added to the photoflo and no squeegee. Most
of the brands on the market contain nothing else, but good idea to
read the label as there appear to be some that have chemicals you
wouldn't want. All I ever see in my local stores is the pure stuff.
you should not need anything fancier.

Good luck

Nick
