I really only have dust and pet dander to deal with, and the pets aren't allowed into the sewing room so it's only what drifts in (which is plenty, since we have 3 mostly-indoor dogs & an indoor cat). I never have windows open in there, either. (2 don't open at all, and the 3rd is hard to reach.)
My rulers all hang on a rail above my cutting table, I've never had to dust them. I guess they get used enough to never build up any noticeable dust! (Or I am just dust-oblivious, which is also possible.)
Most everything else is in drawers - if I start noticing extra lint rolling around in a drawer I usually just blast the drawer out with canned air. I also periodically blast my pen cup that holds all my stilettos and blue water-erase ink pens near my machine. My table tops tend to get dusty in the corners, sometimes I'll bother to wipe those down.
Vacuuming takes care of the rest.
I don't look too closely at the things I have on display on top of my cabinets. They're probably very dusty, but I can't tell from the ground, so that means the dust doesn't exist!
