Step 4: Clean the Fan Blades
If the grille openings are wide enough, use a cloth wrapped around a thin ruler, spatula, or similar tool to reach the blades.
Lightly dampen the cloth with the cleaning solution.
Carefully wipe each blade through the grille openings.
Rotate the blades by hand while the fan remains unplugged.
This allows you to access all blade surfaces without disassembling the fan.
