How can I clean my ceiling fan blades without standing on a chair?

I have an extending microfiber duster. It's amazing and I can bend it to do ceiling fans, under and behind appliances, baseboards, crown molding or where the wall & ceiling meet. The one I have is by Campanelli and I got it on QVC. It "grabs" the dust and is amazing. I purchased a set that has 2 small dusters for furniture and the long one extends to 100". It's great for recessed lighting as well.

They sell telescoping poles with a swiffer type of duster. Would that work for you?
