You may need a ladder or stool to reach the exhaust fan safely. Choose one that is steady and the right height.
Turn Off Power
Before cleaning your kitchen exhaust fan, always turn off the power. This step is important for your safety. It prevents electric shock and accidental fan operation.
Turning off the power also protects the fan’s motor from damage during cleaning. Make sure you know where the power switch or circuit breaker is located.
Locate The Power Source
Find the correct power source that controls your kitchen exhaust fan. This can be a wall switch or a circuit breaker in your home’s electrical panel.

- Use the correct screwdriver size
- Handle clips carefully to avoid damage
Remove The Fan Cover Gently
After loosening screws or clips, pull the cover away from the fan. Do this slowly to avoid breaking the cover or fan parts.
If the cover feels stuck, check for hidden screws or clips before pulling harder. Keep the cover safe for cleaning and reattachment.
Clean The Fan Cover
Once removed, take the fan cover to the sink or cleaning area. Use warm water and soap to remove grease and dust.
