And when you’re dealing with vents and radiators, this dust is propelled into the room. Why it matters: A buildup of dust anywhere harbors allergens. Try to do this: At the beginning and the end of fan season, or every other month if you use the fan year-round. It is shaped to fit around the blades and screws onto an extension pole ($50, ). If, however, you have a very high ceiling that’s out of range-say, 12 feet-use a ceiling-fan duster, like the Unger microfiber duster ($14, ). Use a cotton cloth for residual grime and to dust the base and the light fixture.

Step 4: Standing on an extra-tall stepladder that puts you about a head above the blades, slip the bag or the pillowcase over each blade, pulling it back to trap dust (you can use the same one for all the blades-just keep maneuvering it to find a clean spot). Step 3: Fill a spray bottle with water and 2 tablespoons of distilled white vinegar and use it to spritz the inside of a cloth shoe bag or pillowcase. Try to cover a radius about twice as wide as the blades. Step 2: Spread drop cloths or old sheets on the floor and over any furniture under the fan. Step 1: Tape down the fan’s switch for safety. A dusty fan can send mites scattering to bedding and furniture, so it’s actually a health risk. They contribute to allergies and sinus infections. Why it matters: When dust sits around, dust mites move in. Try to do this: Whenever you’re sick of looking at the bugs. (Consider switching to frosted-glass domes, which camouflage the body count better than clear ones.) Step 4: When it’s dry, reattach the dome. (You can also pop most domes into the dishwasher, says Henning, who does this with all but painted and very delicate covers.) Step 3: Wipe with a sponge, rinse, and dry. Fill with warm water and a squirt of dish soap and let soak. Line the sink with a large dish towel (to prevent breakage) and place the dome on top, open-side up. Step 2: Climb back down and head to the kitchen. With a screwdriver and a cotton cloth in your pocket, climb an extra-tall stepladder (try the six-foot Werner 356 $71, ), which will get you eye to eye with the fixture. Wear an apron with pockets to stash supplies.

Step 1: Turn off the light and tape down the switch for safety. They’re not dangerous to your health, but who wants to look at them? Why it matters: The corpses pile up, especially in summer. Try to do this: Every month or two if you have kids and/or pets twice a year otherwise. Rinse the bag or bin in hot water before reattaching (or toss the bag in the washing machine, then let it air-dry). Put the bag or bin inside a garbage bag and shake out the dust, says Debra Johnson, training manager for the Memphis- based Merry Maids cleaning service.
