A very clever cleaning tip for removing dust from ceiling fans appeared in home improvement legend Bob Vila’s website. 
Dust on ceiling fan blades falls into that “out of sight – out of mind” category. When you do finally take a look, it is amazing how much dust can accumulate on the tops of the fan blades. If you try to use a rag or a feather duster, the dust goes flying all over whatever is under the fan and into the air to settle on everything in the room. The tip explained in the following article involves using an old pillowcase to capture the dust while cleaning the blades.

If you don’t mind paying for a dusting product, a Swiffer® Duster (or store brand version) does a good job of capturing most of the dust rather than just knocking it off the fan blades. If you really don’t want to climb on a stool or ladder to reach the fan, there is also the Swiffer 360⁰ Dusters Extender™ that extends up to three feet. Remember to also dust the top of the fan motor if the whole motor unit is not up tight against the ceiling.
