Difficulty: Moderately Easy
Step1
Unplug the oscillating fan. Vacuum the fan's protective grille. Use the vacuum cleaner's brush attachment to loosen the surface dirt.
Step2
Remove the protective grille. Some oscillating fans use a clipping mechanism to attach the grille, while others use screws. The grille shouldn't be too difficult to remove.
Step3
Take the blade cap off. This will allow you to remove the oscillating fan's blades. Gently wipe the fan blades and grille with a damp washcloth or sponge. For extremely dirty fans, immerse the blades and grille in warm, soapy water and clean accordingly.
Step4
Dry the oscillating fan parts. You can either towel dry them or allow them to air dry. Either way, make sure they are completely dry before you put the fan back together.
Step5
Replace the blade, blade cap and grille.
