Insider Tip

Cleaning your fan regularly will extend the longevity of your machine.


First, remove your fan from its power source by unplugging the power cord. This is crucial because you can become seriously injured if electricity is still running through your fan. Now that this is done, it’s time to learn how to clean fan blades and the housing.


Next, look to see how dirty the blades are. The first step is to use compressed air to blow away the accumulated dust layer. Handheld vacuum cleaners are also great for sucking away loose dust.


After this, you can use soapy water and a damp cloth to clean away anything stuck to the fan blades gently. It is also appropriate to use an all-purpose cleaner as long as you thoroughly rinse the blades with warm water afterward.


Then, dampen a microfiber cloth with warm water and use it to clean the housing and outer parts of your fan. Wipe away any smudges or fingerprints that might be on there.


Failure to clean your fan can result in poor air circulation, lower air quality, and even degrade your fan over time.


You’ll now need to wipe everything down with a clean, dry microfiber cloth, and your fan should be clean. For more specific instructions, please read our article on how to clean a tower fan.
