Swiffer dusters work great, around the toobs (gently!), etc., nothing is better– and they do seem to retain most of the dust. Although I thought I heard somewhere that they are treated with a substance of some kind, but can't confirm this. They don't seem to leave any residue, at least I haven't noticed. Canned air does nothing but blow it back into the air, where it settles right back down where it was.
