Wipe down mini-blinds with a damp dryer sheet. This eliminates the static that causes dust to stick. The same trick works for TV and monitor screens.
Smelly gym bags, closets, ect..
Also works wonderfully for:
EBay sellers that want to keep items smelling fresh- cut a small square off and put it shipping box along with items for customer. -I heard of sellers doing this, they said their customers complimented them on how good the items smell!
