Cooking is an enjoyable and rewarding experience, but dealing with the aftermath—especially the greasy buildup on your kitchen exhaust fan—can be frustrating. Over time, grease, dust, and other particles accumulate on your fan, making it less effective and more challenging to clean.
However, cleaning grease from your kitchen exhaust fan doesn’t have to be a daunting task. With the right approach and some common household items, you can restore your exhaust fan to its original glory. In this ultimate guide, we’ll walk you through every step of cleaning your kitchen exhaust fan in the easiest and most effective way possible.

Why Should You Clean Your Kitchen Exhaust Fan?
Before we dive into the cleaning process, let’s first explore why you should prioritize cleaning your kitchen exhaust fan regularly. While it may seem like a small detail, maintaining a clean fan can have a significant impact on your kitchen’s air quality, safety, and overall cleanliness.
Improved Air Quality
Exhaust fans are designed to remove smoke, steam, and grease particles from the air. Over time, if these particles aren’t filtered properly, they can become trapped in the fan’s vents, causing your kitchen air to become greasy, smoky, and even smelly. Cleaning your exhaust fan ensures the fan can continue performing its primary function—improving air quality by venting out cooking fumes.
Enhanced Fan Efficiency
Grease buildup reduces the efficiency of your kitchen exhaust fan. The more grease that accumulates on the fan blades and filter, the harder the fan has to work to remove the air pollutants. By regularly cleaning the fan, you ensure it works at full capacity, saving energy and improving performance.
Preventing Kitchen Fires
Did you know that grease buildup in kitchen exhaust fans is a leading cause of kitchen fires? The grease trapped in the fan’s venting system can heat up, and when exposed to a spark or flame, it can ignite. Regular cleaning of the exhaust fan helps reduce this risk and keeps your kitchen safe.
Maintaining the Longevity of Your Exhaust Fan
Excess grease and grime can shorten the lifespan of your kitchen exhaust fan. Regular cleaning prevents the buildup of harsh substances that can damage the fan’s internal components, ensuring it lasts longer and functions better.
Now that you understand why cleaning your exhaust fan is essential, let’s get into the nitty-gritty of how to do it properly.
Step-by-Step Process to Clean Your Kitchen Exhaust Fan
Cleaning your kitchen exhaust fan might seem like a huge task, but with a systematic approach, it becomes quite manageable. We’ve broken down the process into easy-to-follow steps, from gathering supplies to reassembling the fan.
Step 1: Gather Necessary Tools and Supplies
Before you begin cleaning, you need to have the right supplies on hand. Here’s a list of what you’ll need:
- Dish soap or degreaser: A heavy-duty degreaser or dish soap is essential for breaking down the greasy buildup.
- Baking soda: Baking soda is a great natural cleaner that can help cut through grease.
- Warm water: Warm water helps dissolve grease and grime more efficiently.
- Scrub brushes: A small brush will help scrub the filters and other components of the fan.
- Microfiber cloths: These are perfect for wiping surfaces without leaving lint behind.
- Gloves: Grease and cleaning agents can be harsh on your hands, so it’s a good idea to wear gloves.
- Ladder or step stool: If your fan is mounted high, a ladder or step stool will help you reach the fan.
- Bucket: To hold the soapy water or degreaser solution.
Having all these tools ready will make the process much smoother and faster.
Step 2: Turn Off the Power and Remove the Fan Cover
Safety should always be your top priority when cleaning appliances. First, turn off the power to your exhaust fan to avoid any accidents. If your fan has a switch, make sure it’s in the off position. Then, carefully remove the fan cover. Depending on your model, the cover might be attached with screws or clips. Use a screwdriver or your hands to detach the cover. Once it’s removed, set it aside in a safe place.
Step 3: Clean the Filters
The filters are the parts of the exhaust fan that get the dirtiest. Over time, they can accumulate a lot of grease, making them harder to clean. Fortunately, they are usually removable, which makes the cleaning process easier.
- Soak the filters: Fill a large bowl or sink with warm water and add dish soap or a degreaser. If you prefer a more natural solution, mix equal parts baking soda and water. Place the filters into the solution and allow them to soak for about 15-20 minutes.
- Scrub the filters: After soaking, use a scrub brush to remove any remaining grease and grime from the filter. You may need to apply more soap or degreaser to areas with stubborn grease buildup.
- Rinse and dry: Once the filters are clean, rinse them thoroughly with warm water. Allow them to dry completely before reinstalling them into the fan.
Step 4: Clean the Fan Blades
After cleaning the filters, the next step is to clean the fan blades. Depending on the type of fan you have, the blades might be coated in grease, dust, or a combination of both.
- Wipe down the blades: Use a microfiber cloth or sponge dipped in warm, soapy water to wipe down each blade. Be careful not to bend the blades or apply too much pressure. Gently scrub away the grease and dirt.
- Use a degreaser: For tougher grease, apply a degreaser directly to the fan blades. Let it sit for a few minutes before wiping it off.
- Dry the blades: Once the blades are clean, dry them with a microfiber cloth to prevent water spots.
Step 5: Clean the Fan Motor and Housing
The motor and housing are often overlooked, but they can accumulate grease and dust over time. Cleaning them is essential for maintaining the fan’s efficiency.
- Wipe down the motor: Use a dry microfiber cloth to wipe the exterior of the motor and housing. Be cautious not to get water inside the motor.
- Use compressed air: If you have compressed air, you can use it to blow out any dust or debris from the motor area.
- Check the vents: Make sure the vents around the motor are clear of grease or dust. Use a small brush to dislodge any debris.
Step 6: Reassemble the Fan and Test
Once all the components are cleaned and dried, it’s time to reassemble your exhaust fan. Carefully place the filters back into their designated slots and reattach the fan cover. Make sure everything is securely fastened before turning the fan back on. Finally, switch the power back on and test the fan to ensure it’s working properly.
Natural Cleaning Solutions for Kitchen Exhaust Fans
While commercial degreasers are effective, they often contain harsh chemicals that can harm your health and the environment. If you’re looking for a more eco-friendly approach, several natural solutions can effectively clean grease from your kitchen exhaust fan.
Baking Soda and Vinegar
Baking soda and vinegar are two powerhouse ingredients for cleaning grease. Baking soda helps cut through grease, while vinegar acts as a natural degreaser and disinfectant. To make this solution, mix a paste of baking soda and water, and apply it to greasy areas. For tougher spots, spray vinegar on top of the baking soda paste and watch it fizz. Let it sit for a few minutes before scrubbing.
Lemon and Baking Soda
Lemon is a natural cleaner that can break down grease and leave your kitchen smelling fresh. Combine lemon juice with baking soda to create a paste. Apply this mixture to greasy areas on the fan and let it sit for 10-15 minutes. Scrub the areas with a brush or sponge and rinse clean.
Dish Soap and Hot Water
Sometimes, all you need is a simple solution of dish soap and hot water. The dish soap helps to break down the grease, while the hot water makes it easier to dissolve grime. Soak the fan’s filters and scrub the blades with this mixture to remove grease effectively.
