Black dust on fan blades.

People often ask why spider webs and dust can be seen on the fans. Step 2 wipe the fan mount and housing with a damp cleaning cloth or microfiber cloth to remove dust working from the ceiling down toward the blades. The air always has a great deal of dust in it larger particles that you can see and also microscopic ones. 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.

Why do some fans have this buildup and other s don t. Over time a large volume of the circulating air hits and collects on the blades of the fan. 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.

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. Once they re all dry apply your paste car wax. Soot deposition is most likely to occur on wall and ceiling surfaces in rooms where candles are burnt. But they must understand that there is a lot of dust in the circulating air.

If the register is closed the air is forced along the ceiling and the next thing you know you ll start to see black buildup across your ceiling. 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.
