    I spent part of this morning polishing my glass carrier. I still ended up with white spots on the prints. I think the negatives are clean but I'll check them again later. I'm also going to take the whole head apart and polish the condensors. Other then that what am I missing?

    I have the same trouble, found that my cleaning was attracting static - and dust.....

    Now do a brief wipe with an anti-static cloth, followed by a blast of air.

    Still need Spot pens, but not as much

    I like the Kinetronics 4" brush. I'll usually brush off the glass and neg each time I insert a new neg in the enlarger (or scanner for that matter), and if it needs some Dust-Off, I'll use that too.

    I periodically clean my glass carriers with isopropyl alcohol - once or twice a year they get a bit hazy.

    Other than that I use compressed air to blow out dust. I try to avoid removing the carriers from the enlarger to minimize further dust entry.

    The most important dust control factor in my darkroom is a large, freestanding HEPA filter. It's designed for a room three times the size of my darkroom, which doubles as a spare bathroom/laundry room (so you can imagine the dust on laundry days).

    Last winter I had horrible dust problems. It got so bad I gave up on trying to print for two or three months. The HEPA filter cleared up the problem.

    I also wear a bandana on my noggin while in the darkroom. I have long hair which tends to shed a bit due to a bad thyroid condition. I also have a beard and probably should wear a face mask but so far I haven't seen any need to go to such extremes.

    As Ann suggested, dust off the paper before making the exposure. I keep an Asian hake brush in the darkroom for that purpose, tho' sometimes I'll just use the edge of my palm or a squirt of compressed air.

    To minimize problems on my negatives I use filtered or even distilled water whenever feasible. Our water comes from a rural well tapped into a limestone basin - I'd get actual chunks of lime scale if I didn't filter the water. There's also a brine type water softener in the well house.

    My darkroom in in my garage and dust is a challenge. My solution was to biy a medical humidifier (the ones you put in a childs room when they have a cold). I run it for about 15 minutes before starting a session. Works really well, and was a very cheap solution. Most drug stores carry them.

    I'm in the basement so it should be humid enough. OTOH Something I noticed awhile back. When the heat is on one of the vents blows straight down into my fixer tray. So with the furnace on now it must be blowing dust all around

    The trick for me is getting very fine water droplets into air. Being heavier than air pulled the dust to the ground.

    I turn the beast off a few minutes before starting a darkroom session.
