Looks like blowing off the rolling stock and buildings then vacuuming up might work.maybe get one of those tiny vacuums for key boards like computer key boards. canned air works too but spreads dust every where as well. but it should dust off the buildings nicely.

Thanks for the link, too. That should work well as long as it doesn't blow the buildings apart :laugh:
