How to Clean a Bathroom Exhaust Fan with a Light Safely

While cleaning the bathroom, most of us forget to give attention to the exhaust fan. 

But cleaning this part is also necessary as they pull out excess humidity, reduce odors, and prevent mold growth. Letting these issues persist can lead to serious health hazards that can cost you a lot. 

Like many people, if cleaning your bathroom fan hasn’t made your to-do list for lack of attention, this blog is for you. With our simple guide, you will be able to clean your bathroom’s exhaust fan and wonder how simple it is. So let’s get on it.

Supplies and Tools You Will Need

• Stepstool/Stepladder

• Screwdriver

• Gloves

• Eye protection/Goggles (so that dirt doesn’t get to your eyes)

• Vacuum or duster

• Microfiber cloth

• Soft bristled brush (you can use an old toothbrush)

• Cleaner (you can use dish soap as well)

• Dry towel

Optional:

• Can of compressed air

• Replacement bulb (if yours is dim or dead)

Pro Tip: Use an old cloth or spread a sheet to cover the floor and catch any dust that comes loose.

Step-by-Step Guide to Cleaning Your Bathroom’s Exhaust Fan With Light

Cleaning your bathroom fan isn’t as hard as it looks. Here are the simple steps to help you clean your fan with ease:

Step 1 – Turn Off the Power

Safety should always be your first priority whenever you are dealing with something that runs on electricity. On average, 400 electrocution deaths and 4,400 injuries occur every year in the U.S. because of electrical risks. So, before anything, cut off the power to your bathroom fan- 

• Turn the fan switch off

• Go to the breaker box and turn off the breaker for the bathroom

• Test with the screwdriver if your exhaust fan has any unwanted electricity flowing

After being fully assured that you won’t get shocked while handling wires or cleaning around the motor, go to the next step.

Step 2 – Remove the Exhaust Fan Cover

Place the stepstool or stepladder up the spreadsheet and under the exhaust fan. Do the following after placement-

• Climb the stepstool and gently pull down the fan cover. Most covers pop off by pressing the metal clips inward.

• If the cover has screws, use a screwdriver to take them off.

• Hold one hand underneath the cover while removing it to avoid it falling. 

• Once it’s off, set it aside for cleaning.

Pro Tip: Avoid standing directly under the fan cover by angling your ladder slightly to one side to keep dust from falling on you.

Caution: For safety purposes, have someone beside the stool so that there are fewer chances of you falling from there.

Step 3 – Remove the Light Bulb

If your fan has a built-in light, now’s the time to remove it-

• Unscrew the bulb carefully and place it in a safe spot. 

• If the bulb is dirty, wipe it gently with a dry cloth. 

• If it's burned out or discolored, consider replacing it.

Caution: Make sure the bulb has cooled down before handling it.

Step 4 – Take Out the Fan (If Possible)

Some fans allow you to remove the whole fan unit by unscrewing a few brackets. If yours is removable-

• Unplug the motor connector and slowly pull the unit out. 

• Be cautious not to tug on wires or damage the fan blades.

If the unit isn’t removable, do not worry about it. You can still clean it in place.

Step 5 – Vacuum the Blades and Dust the Fan Components

Use a vacuum with a brush or crevice attachment to suck out as much loose dust as you can. After that-

• Pick a dry cloth or rag

• Give a primary cleaning/dusting off the inside of fan components, including the blades

Pro Tip: Be gentle with the fan blades. They are lightweight and can bend or snap with too much force.

Step 6 – Wipe Down All Surfaces

Arrange mild warm water and add drops of your preferred cleaner. Soak a micro fibre cloth in it and-

• Wipe the fan housing, motor edges (if accessible), and nearby ceiling areas.

• Avoid dripping water inside the motor housing. If needed, use a dry cloth to buff off any remaining moisture.

If your fan blades or edges have strong stains or grim- 

• Pick up the brush and soak it in the cleaner solution

• Scrub as much as you can, but gently, until the dirt gets removed

Since this isn’t something you’ll do often, be as thorough as you can.

Step 7 – Clean the Fan Cover and Light Cover

Soak the cover (and light lens, if detachable) in a bucket of warm water mixed with a few drops of dish soap. After that- 

• Let them sit for a few minutes

• Scrub with your soft brush to remove grime

• Rinse with clean water and dry with a towel or leave them to air-dry

After finishing all the cleaning, let the components dry for a while.

Step 8 – Reassemble the Fan and Reinstall it

Once all parts are dry:

• Reinstall the fan motor (if removed)

• Reconnect any wiring

• Screw the fan housing back in place

• Put the light bulb back

• Snap or screw the cover into position

Now restore power at the breaker and test your fan. It should run quieter and brighter.
