Hucho's book has a chapter just about vehicle soiling. Unfortunately the commonly seen examples are trade offs between increasing drag and "cleanliness" for lack of a better word.

Some people claim vortex generators help with soiling on the back of vans/hatchbacks. The airtabs style don't seem to affect MPG one way or the other, but perhaps they may help with dust.
