Cleaning your kitchen wall exhaust fan is essential for maintaining a clean and healthy kitchen environment.
Over time, kitchen exhaust fans collect grease, dust, and debris, reducing their efficiency and potentially becoming a fire hazard.
Here’s a step-by-step guide on how to clean your kitchen wall exhaust fan to keep it running smoothly. 
What You’ll Need:
- Screwdriver
- Dish soap
- Baking soda (optional)
- Warm water
- Degreaser or vinegar
- Scrub brush or old toothbrush
- Microfiber cloths or paper towels
- Bucket or large basin
- Cleaning gloves (optional)
- Old newspaper or plastic sheeting (to protect the surrounding area)
Step-by-Step Guide to Cleaning Your Kitchen Wall Exhaust Fan
1. Turn Off the Power
Safety first! Make sure to turn off the exhaust fan before starting the cleaning process. You can either unplug it from the power outlet or turn off the circuit breaker if it’s hard-wired.
2. Remove the Exhaust Fan Cover
- Locate the screws or clips holding the exhaust fan cover in place.
- Use a screwdriver to carefully remove the screws or unfasten the clips. Be sure to keep the screws in a safe place so you can reassemble the fan later.
- Once the cover is removed, take it to a sink or cleaning area for washing.
3. Clean the Exhaust Fan Cover
- Soak in warm soapy water: Fill a sink or basin with warm water and a few drops of dish soap. If the cover is especially greasy, you can add some baking soda for extra cleaning power.
- Scrub the cover: Use a scrub brush or an old toothbrush to scrub away grease and grime from the cover. Pay special attention to any corners or crevices where dirt tends to accumulate.
- Rinse and dry: Once the cover is clean, rinse it thoroughly with clean water and allow it to air dry, or use a microfiber cloth to dry it manually.
4. Clean the Fan Blades
Fan blades are prone to collecting grease and dust over time. Here’s how to clean them effectively:
- Wipe down with degreaser: Spray a degreaser (or a solution of vinegar and water) onto a cloth or directly onto the fan blades. If you prefer natural cleaning solutions, white vinegar mixed with warm water works well to break down grease.
- Scrub the blades: Use a scrub brush or a microfiber cloth to scrub the blades, removing grease, dust, and debris. For hard-to-reach areas, an old toothbrush can help you get into the tight spaces.
- Rinse and dry: After scrubbing, wipe the blades with a damp cloth to remove any remaining residue, and then use a dry cloth to wipe them down.
5. Clean the Fan Housing and Motor (Carefully)
The fan housing and motor also accumulate dust and grease. However, it’s important to be cautious when cleaning around the motor, as it’s an electrical component.
- Wipe the housing: Use a damp cloth with a degreasing solution or soapy water to wipe down the inside of the fan housing, but avoid getting water or cleaner on the motor.
- Dust the motor: If the motor itself is dusty, use a dry cloth or a can of compressed air to remove any dust or debris. Do not spray liquids or cleaners directly onto the motor, as this could damage the electrical components.
6. Clean or Replace the Filter (if applicable)
Some kitchen exhaust fans come with a removable filter designed to trap grease and odors. If your fan has a filter, follow these steps:
- Remove the filter: Carefully take out the filter from its housing. If the filter is disposable, replace it with a new one.
- Clean the filter: If the filter is washable, soak it in warm soapy water mixed with a degreaser or vinegar. Let it soak for 15-20 minutes, then scrub gently with a brush to remove any grease buildup. Rinse thoroughly and let it air dry before reattaching it.
7. Reassemble the Exhaust Fan
Once all components are clean and dry, it’s time to reassemble the fan.
- Replace the fan cover: Use the screws or clips you removed earlier to reattach the fan cover.
- Turn the power back on: Plug the fan back in or switch the circuit breaker on to restore power.
8. Wipe the Surrounding Wall
Don’t forget to clean the area around the exhaust fan. The walls near the fan often collect grease and dust as well.
- Spray degreaser or vinegar solution: Apply a cleaning solution directly to the wall, especially in areas with visible grease splatters.
- Wipe with a cloth: Use a microfiber cloth to wipe away any grease or dirt, leaving the wall clean and free of residue.
Tips for Keeping Your Exhaust Fan Clean:
- Clean regularly: Depending on how often you cook, aim to clean your exhaust fan at least every 3-6 months. If you do a lot of frying or cooking that produces grease, you may need to clean it more frequently.
- Wipe down after heavy use: After cooking particularly greasy meals, wipe the exhaust fan cover to prevent buildup.
- Use a degreaser: For heavy-duty grease, using a commercial degreaser can make cleaning faster and more effective.
Conclusion
Cleaning your kitchen wall exhaust fan is a relatively simple task that can significantly improve the cleanliness of your kitchen and the efficiency of your fan.
By following the steps above, you can remove built-up grease, dust, and debris, ensuring your fan operates effectively and your kitchen stays clean and odor-free. Regular maintenance will extend the lifespan of the exhaust fan and prevent potential fire hazards caused by grease buildup.
