We eliminated the attic in my 1930's cape and cathedraled the ceiling. What was dark and dank is now bright and full of light. There are now exposed beams and a paddle fan where cob webs and darkness once loomed.
Now, dust settles on the beams and the paddle fan. So, periodically, they need to be cleaned. I really don't want to have to drag a huge ladder into the house for this. You can buy a telescoping paddle fan cleaner. And, it does loosen any caked on dirt that may have collected on the paddle fan. But it really doesn't eliminate the dust (in fact, the dust it loosens mostly gets flung into the air instead of being captured by the paddle fan brush bristles : ).
Now, the new Swiffer 360 duster is a wonderful thing indeed. And although there is a telescoping feature, it can't be extended enough to reach my beams and paddle fan. So, I just decided to get out the good old duct tape and fasten the Swiffer 360 to the end of the paddle fan cleaner (which reaches these high places).
Lough and behold, this little solution let me clean both my paddle fan and beams fully inside of 10 minutes without throwing the dust into the air, but capturing it in the swiffer fabric (I did go through a few of these.... it had been quite a while since this cleaning was last done : ).
So for those of you with paddle fans &/or exposed beams, "Try it, you'll like it!"
