I'll be the contrarian here. I think I know why every suggestion here works.
Dust doesn't stick to film as it dries. It drains off with the sheet of water.
I hang my film without benefit of any protection after dipping in a solution of PhotoFlo and filtered water.
My darkroom in the garage is "infested" with dust. When the sun comes in late afternoon I can see the dancing particles. Yet my dry negatives look clean and rarely have any significant dust issues when I print.
