Step 1  Gather Your Supplies

Before starting the cleaning process, gather all the supplies, including:

  • Screwdriver
  • Vacuum cleaner with a brush attachment
  • Soft cloth
  • Mild detergent
  • A small bowl of warm soapy water
  • Safety goggles
  • Dust mask

Turn Off Power

No one would criticize you for taking excessive precautions. First of all, disconnect power to the exhaust fan at the relevant circuit breaker box. This is to ensure that any electrical appliances cannot be activated accidentally while you are working. If in doubt which breaker controls the fan, the easy solution is to swtich off the main power to the bathroom.

Turn Off Power

Remove the Fan Cover

Remove the Fan Cover

Most of the covers for exhaust fans come with clips in addition to screws that hold them in place. If your model comes with clips, squeeze them lightly to release the cover. Remove the screws using your screwdriver, if it is not the case. After that, lower the cover down, decompressed, and put it aside.

Clean the Fan Blades

Holding the vacuum cleaner vertically with the brush tube, lightly artifact or blow out the fan dust and debris. If there is accumulated dust, you should wipe it using a soft cloth moistened with a little bit of detergent. Be careful that the cloth is not dripping wet to prevent the motor from being affected. You can leave the solution on for several minutes and then wipe it off for dried-up dirt.

Clean the Cover

Using water or a damp clean cloth, clean the removable cover. Remove the offending cover and wash it in warm water. Alternatively, if heavy in use, a few covers may need to be left in warm water to loosen stuck grime.

Clean the Housing and Motor

With the fan now accessible, it's time to clean the housing. Use the hoover to remove the leftover dust and debris from the interior. Take care not to touch the motor components. Any soot on the motor should be removed very carefully with a dry rag.

Reassemble the Fan

Once everything is done and all the parts are clean and are dry, the fan cover is in place. This, for most covers, was the last step as, if it was fitted to a bracket using screws, that rim has to be tightened in case the cover falls off.

Restore Power and Test

Finally, the fan has been properly assembled, so it now goes to the circuit breaker and switches on the power. Turn the fan on and check to see if it is running correctly. Observe the sound during the unit's operation because any strange sounds will indicate malfunction.
