Hi Pete,
When my figures get a little a dusty I delicately brush them with a (dry) paint brush. I use a paint brush that has very soft, long and flexible bristles. The bristle head is about 3/4" wide. I use a the brush with a "flat" bristle style, but a "fan" bristle style might actually be a better choice.
Whichever bristle style you use, whether flat, fan, "bright", etc... you just definitely don't want to use anything with stiff bristles. They are more likely to scratch the surface of your figures and can even lift the paint off! (Note: some manufacturer's seal their figures better than others; some have had paint adherence issues and great caution must be taken when handling and/or cleaning).
I just very softly brush the dust away being careful not to get the bristles snagged on the accessories of the figure. I don't "stab" the figure with the brush....I just very gently stroke away the dust in one direction. This method seems to work good for me. A lot of my figures are out in the open air, so occasionally I do have to "dust" them off. The figures I have behind glass require much less cleaning, of course.
One thing that really helps is to keep your figures in an area where there is little foot traffic. The foot traffic sends a lot of dust particles into the air and onto your figures. I'm lucky to have a small "man cave" room where I keep all of my open air stuff on display. I hope this helps!:smile2:
