How to Clean Dust Off of Ceiling Vents
- 1). The simplest method is to use a vacuum cleaner with the extension and brush attachment to suck the dust off of your ceiling vents. Tape the brush attachment to the extension with duct tape so that it doesn't get knocked off when you are cleaning the vent.
- 2). For a more thorough cleaning, put on your goggles and dust mask and use a broom to clean the dust off of the vents, then sweep it up from the floor.
- 3). The most labor-intensive method is to climb a ladder so you can reach the ceiling vents and use a screwdriver to remove the vents. Make sure you keep the screws in a safe place.
- 4). Wash the vents thoroughly with the de-greaser and hot water. Dish soap works for mild dust; use TSP or Mr. Clean for kitchen grease. When they are clean, dry the vents completely, and replace them.
