How to Clean an Electric Fan?

Update:15 Aug 2025

During the scorching summer heat, electric fans are essential cooling tools for many households. However, over time, fans accumulate dust and dirt, which not only affects airflow but can also negatively impact your health. Regularly cleaning your electric fan not only ensures smoother operation and longer life, but also keeps indoor air cleaner and fresher.

Why should you clean your electric fan?

When your electric fan is running, its blades pick up dust, pollen, hair, and other particles from the air, which collect on the blades and fan grille. Over time, this dust forms a thick layer of dirt, reducing airflow and increasing noise. It can also cause the motor to heat up and increase power consumption. Even more problematic, this dirt can be re-blown into the air, potentially causing allergies, coughing, and other problems. Therefore, regular cleaning of your electric fan is essential.

Gather the following tools before you begin:

  • Screwdriver (or Phillips-head knife)
  • Soft cloth or microfiber cloth
  • Vacuum cleaner or hair dryer
  • Mild detergent (dishwashing liquid or diluted vinegar)
  • Water
  • Old toothbrush or small brush
  • Bucket or basin

Step 1: Unplug the fan and disassemble it

Safety first. Unplug the fan to prevent electric shock. Depending on the fan model, use a screwdriver to remove the grille (some are secured with clips; simply follow the instructions in the manual). Once the grille is removed, you will see the fan blades.

Step 2: Clean the grille and blades

If there is a lot of dust, first use a vacuum cleaner or hair dryer to remove any loose dust. Then, soak the grille and blades in a basin of warm water and a little detergent for a few minutes to loosen any dirt. After soaking, use a soft cloth or old toothbrush to scrub every corner thoroughly. For parts that cannot be cleaned directly with water, wipe them with a damp cloth. Finally, rinse thoroughly with clean water and dry with a cloth or air dry.

Step 3: Wipe the motor housing

After the fan blades and grille have dried, wipe the motor housing and base with a slightly damp soft cloth. Be careful not to let water get into the motor to prevent damage. Use a small brush or cotton swab to clean the crevices. This area is often overlooked, but it can also harbor a lot of dust.

Step 4: Reassembly

After all components are completely dry, reassemble them in the reverse order of disassembly, ensuring the screws are tightened and the grille is securely locked. Check again before plugging in to ensure that it is installed correctly. This cleaned fan will look clean and perform better.

Step 5: Routine maintenance

To reduce dust accumulation, it's recommended to wipe the exterior with a damp cloth every one or two weeks and thoroughly disassemble and clean the fan every three months. If the fan has a dust cover, use it to reduce the frequency of cleaning.

When to see a professional

Common minor repairs and cleaning procedures can be handled yourself. However, if the fan makes unusual noises, the motor becomes severely overheated, or won't turn, or you're unsure how to disassemble it, it's best to seek professional repairmanship to avoid damaging the machine.
