How to Clean a Bathroom Fan

By : Georgia
There is no denying that an exhaust fan is one of the most overlooked items when it comes to cleaning the bathroom. It is extremely imperative to thoroughly clean the vents and filters of the fan as it helps in removing excess moisture, stops breeding mould and mildew and maintains the air quality. That’s why it is always recommended to run the fan after the shower for 10-15 minutes. But for that, you need to keep it free from dust and grime. Cleaning of a bathroom fan is vital because when air passes through the vents, dust accumulates on the grill cover and the fan motor, which needs to be removed every six months. But what if you are moving out of your rental premises? If you are at the end of your tenancy, then hire professionals for the attention-to-detail vacate cleaning in Perth. They know how to get the cleaning job done on time without even giving you a hint of stress. While hiring a professional cleaner is an ideal way, you can also clean your bathroom fan on your own. Here is the complete process of cleaning the exhaust fan:

1. Preparation is Important

It is always good to prepare yourself before getting into the cleaning process. Since your bathroom fan is located on the ceiling, make sure you arrange everything on time. You might need a stepladder so that you can reach the ceiling easily. Also arrange the vacuum cleaner, a brush attachment, long handle, cleaning duster/microfiber cloth and other supplies for safe and secure cleaning of your exhaust fan. Apart from this, also remove the cover of the fan using a screwdriver. Tip: Keep the screws in a safe place before getting into the cleaning process. And if the fan is plugged into an outlet, don’t forget to unplug and unscrew the pins.

2. Deep Clean the Parts of an Exhaust Fan

A bathroom exhaust fan is usually made up of three parts: the fan blades and motor, the cover, and the housing. If you want to improve the air quality inside your bathroom, you need to remove the build-up dust from each part thoroughly. But before this, turn the fan off at the circuit breaker or the switch. Remove the cover from the ceiling by pressing the spring-loaded wire clips. Then remove the clips attached in the fan housing. Learn how to clean the major parts of a bathroom fan:
Clean Vent Cover
The vent cover of your exhaust fan collects the dangerous dust mites, germs, grease and grime. So, the first task is to clean it thoroughly using safe and sound products. Here is the quick method of eliminating dust from the vent cleaner:
  • Soak the cover in a tub of hot dishwashing water.
  • Leave it for 10 minutes.
  • Meanwhile, you can clean the fan blades.
  • Scrub the build-up dust and grime away using a damp microfiber cloth.
  • Dry the vent cover before reassembling it.
Quick Tip:
Hot soapy water breaks down the tough stains, dust and grime – which makes your scrubbing job easier.
Cleaning the Fan Blades
Don’t forget to twist the motor and fan assembly to disassemble it from the exhaust vent. After that, you need to follow these tricks:
  • Remove dry dust from the fan blades using a microfiber cloth
  • Prepare a cleaning solution by mixing ¼ ammonia, 3 teaspoon baking soda and 1 cup of warm water.
  • Dip the microfiber cloth in the solution and wipe the fan blades. Also, cleaning the motor.
  • For hard-to-reach areas, use a vacuum attachment and fetch all the collected dust.
  • If the fan fixed on the ceiling, use the vacuum cleaner to remove the debris.
If this seems time-consuming task, especially at the end of your lease period, hire trained cleaners in Perth. They will come to your place and clean the entire premises according to the approved  tenancy checklist.
Clean the Fan Housing
This is one of those tasks that you may want to skip due to the complexities. But with the right technique, you can achieve it easily. All you need to do is:
  • Vacuum the interior of the exhaust vent using a crevice attachment.
  • Make sure you remove the dust from brackets that hold the fan in place.
  • Thoroughly eliminate the dirt particles and repeat the process for better results.
  • You can also use a brush attachment in place of a crevice attachment.

3. Vacuum the External Port

Once you are done with the entire cleaning process, be sure you clean the exterior vent of your exhaust fan. With the help of the ladder, reach the height of the exterior part of your fan and wipe off the dirt using a damp cloth. Here, the purpose is to remove built-up dust from the other end of your fan pipe. So, do it carefully and improve the air quality.

4. Re-assembling the Fan

This step is all about bringing the fan and motor to the housing area and fixing it with the screws and brackets. With the use of your fingers, move the fan back to ensure it is not hitting anything. Now, plug the fan into the given outlet, if required. Once the cover gets completely dry, fix it to the bathroom fan. Press the cover and secure it with clips. This is how you can remove the dust and grime off your exhaust fan without even using harsh and expensive products.
