Floor fans are dust magnets and the dust is often clearly visible on the fan blades. Not only is a dirty floor fan unsightly, the dust buildup can be irritating for people with allergies. It is necessary to clean floor fans periodically to remove this buildup from the fan blade and other parts of the fan. Washing floor fans regularly will not only keep the dust count lower in your home, but will also increase the lifespan of the floor fan. The easiest way to clean floor fans is by disassembling the fan so you can reach all of the parts.
Unplug the floor fan from the electrical outlet.
Use a Phillips screwdriver to remove the front grill from the back grill. Some fans will not have screws securing the front and back grills. Instead, use your fingers to pop off the clips holding the front grill to the back grill, and then lift up on the front grill to remove it from the base.
Turn the blade cap clockwise to unscrew it, and pull it off. The blade cap is situated right in the center of the fan blade. Slide off the fan blade from the back grill after removing the blade cap.
Remove the back grill nut from the back grill with your fingers or a wrench, depending on how tight the nut is secured into place. Slide off the back grill from the base of the fan.
Fill a bucket with warm water. Add a few drops of mild dish soap, and use your hands to mix up the soap and water.
Dip a rag into the soapy water and wring it out well. Wipe down each part of the fan that you disassembled with the rag and soapy water. Rinse and wring out the rag often while cleaning the fan parts.
Set the fan parts on a towel to dry. You can help the fan parts dry quicker by wiping each part down with a dry rag. Make sure that there is no moisture on the fan parts before reassembling.
Put the fan back together by using a reverse order of the instructions for disassembling the fan.
