Ceiling fans can easily become very dirty in the dry desert winds of Tucson, Arizona. In Tucson, the sun, the heat, and the dust are constant adversaries of the real estate owner. These white fan blades showcase a myriad desert dust and grime, while wooden colored blades, or certain darker colors, do not give up their dirty secret so easily. Be sure you look - your buyers will be! To clean these, start with a brush attachment on a vacuum cleaner nozzle. Then use an appropriate solution to remove the balance of the dirt. If it's called for, finish up with some spray-on wax.
