Black Dust On Fan Blades

Why do some fans have this buildup and other s don t.

Black dust on fan blades.

The black dust may be due to deteriorating duct liner materials in your heater or air conditioner and in some cases your cold air returns. But they must understand that there is a lot of dust in the circulating air. Once they re all dry apply your paste car wax. You don t want to lather it on but make sure it reaches every part of every blade.

The air always has a great deal of dust in it larger particles that you can see and also microscopic ones. Next you re going to make sure that each blade is dry. People often ask why spider webs and dust can be seen on the fans. Soot deposition is most likely to occur on wall and ceiling surfaces in rooms where candles are burnt.

Over time a large volume of the circulating air hits and collects on the blades of the fan. Stand on a step stool or ladder to reach the fan blades. Additionally fan blades move rapidly through the air rubbing and brushing against air molecules and pushing them out of the way. This same thing happens to the leading edges of your ceiling fan blades.

Most of the dust particles that are floating in your house has some sort of electric charge which can often cause dust molecules to attract together hence the dust bunnies underneath your bed. I suggest you use each paper towel until it gets dark and starts smearing dust or until you move on to the next fan blade whichever comes first.
