Turn the fan to the off position and unplug it from the outlet.
Remove dust from the fan grill using a vacuum cleaner with a brush or crevice tool attachment. The attachments will help to clear dust between the individual openings in the fan grill.
Wipe away any remaining dust or residue with a soft cloth. Wipe the cloth over the Vornado fan's grill. For sticky stains, slightly dampen the cloth with water and rub it over the area.
Clean dust from the electronics grill using an electronics vacuum. An electronics vacuum has just enough suction to remove dust without harming the electrical components behind the grill. Run the electronics vacuum several times until all dust is removed.
