How To Remove Oil Stains On The Ventilation Fan

How To Remove Oil Stains On The Ventilation Fan

The ventilation fan in the kitchen is one of the places where you don’t clean it often. Many people have difficulty cleaning at the end of each year because of the oil stains. You can utilize various methods around the house to solve this problem.

To tell the truth, if you keep the points, you can cleanly remove stubborn oil stains. You can clean your exhaust fan with soapy water if the oil is not too bad. To do this, you only need to prepare a solution of warm water and soap and clean your fan using it. A clean exhaust fan will be available once you have given it a last wash with regular water.

Firstly, Disassemble the ventilation fan

Whatever method you choose, preparation is standard. It’s unfamiliar, so it’s hard to touch even if you want to clean it, but you can easily disassemble it by the following procedure.

1. Turn off the power

First, turn off the power and turn off the ventilation fan. If possible, unplug the switch so you can rest assured if you accidentally touch the switch.

2. Remove the filter

Put on rubber gloves and use a screwdriver to remove the filter. How to remove it depends on the model, but this time the ventilation fan removed the filter just by turning one screw. Place the removed filter on the floor with newspaper or put it in the sink.

3. Remove the cover and fan

Remove the cover that secures the fan at the back of the filter. It’s pretty dirty, so it’s a good idea to wash the cover even if you don’t wash the fan. If you want to wash the fan, turn the screw on the back of the cover to remove it.

Remove oil stains on the ventilation fan with a detergent.


  • Detergent
  • Rubber gloves
  • Unnecessary cloth
  • Toothbrush

To clean the ventilation fan, it is recommended to use a detergent that is effective against oil stains. Oil stains are acidic and can be easily removed with the opposite detergent.

If you don’t have a detergent, you can use a mixture of dishwashing or baking soda, but the oil stains on the ventilation fan are pretty tough, so using a special detergent can clean it without any hassle. You can also use it for cleaning other places, so it is convenient to have one as a trial.

Basic procedure

Oil stains on the ventilation fan are attached to the main body and the surrounding cover. It’s best if you can clean the inside, but basically, you don’t need to disassemble. All you have to do is clean it within reach.

1. Preparation before cleaning

First, turn off the power, so the fan does not start moving during cleaning. Alkaline detergent, which firmly removes stubborn oil stains, may remove the oil necessary for the skin when touched directly, so it is safe to wear rubber gloves in advance.

2. Wipe the front and back of the hood

Spray the detergent directly on the inside and outside of the hood and wipe it off with a clean cloth. Removing the sticky oil stains is more accessible by wiping them off after leaving them for 5 to 10 minutes. You will be able to remove stubborn stains after a while. At first glance, it didn’t look so dirty, but even a light wipe turned the cloth black. The sticky feel returned to smoothness.

3. Remove the metal filter and wash

Remove the filter on the suction port. How to remove it depends on the model, but removing the screws with a screwdriver was all right. Move the removed parts to a washing place such as a sink and spray Magic Lin directly on the oil stains. Again, leave it for 5-10 minutes and wait for the detergent to penetrate. It is convenient to take a picture when you put it back because you will not know where to attach the removed parts.

4. Wash the filter before installing

Scrub the filter you have left on with a sponge-like washing dish to remove oil stains. The ventilation fan filter, which was sticky and dirty, became so shiny after waiting for about 5 minutes. Wipe it dry and wipe off the water, install it again, and you’re done.

Inside stains

Sometimes you want to thoroughly clean the inside, such as the fan of the ventilation fan. Cleaning may seem complicated, but you can do it at home if you know how. Please practice the inspection at the time of general cleaning.

1. Remove the fan

First, remove the filter, and then remove the cover that covers the fan. Once the cover is removed, twist the centre screw counterclockwise to remove the fan. Be careful as the fan is oily and slippery. If it’s difficult to remove the filter or fan, it’s enough to ask someone to help you or remove the oil stains on the inside and outside of your kitchen hood.

2. Wash the filter with the fan on

After removing the fan, apply detergent like a filter and leave it for 5 to 10 minutes. It is efficient to do it together with cleaning the oil stains on the filter.

3. Wash inside

There are also oil stains on the place where the fan was attached, so wipe it off with a cloth sprayed with an alkaline detergent. However, there are cases where thick oil stains harden and are challenging to clean. Even if it is a little dirty, there is no problem in operation, so you do not have to clean it forcibly. This time, I just wiped it gently with a cloth moistened with detergent.

4. Rinse off the fans that have been left behind

Scrape off the dirt on the fan with a sponge and rinse with lukewarm water. The sponge gets very dirty, so it is recommended to use a worn one. After pouring, wipe it dry like a filter.

5. Put back the fan and filter

Once the fan and filter are dry, put them back in, and you’re done. If it goes smoothly, it will take about 30 minutes. The dirt on the fan is quite stubborn, so the trick is to “keep it on.” If it is filthy, try adding more detergent or taking a more extended soaking.

You can clean oil stains on the ventilation fan with baking soda!

For those who do not want to use strong detergent, it is recommended to use “baking soda”, which has alkaline properties, instead of detergent for cleaning. Baking soda is a naturally occurring ingredient safe enough to be put in your mouth without harm. It is recommended to mix it with hot water and soak it. It will take some time, but it will clean it up.

1. Make a soaking liquid

Prepare a large container to hold a filter and fan, and store hot water. Dissolve 2.5 tablespoons of baking soda in 500 ml of hot water.

2. Keep up

Put the removed parts together and leave them on overnight.

3. Scrub

Take it up and rub it with a sponge to remove oil stains.

4. Dry

Dry and drain, and you’re done. If you use “Sesquicarbonate Soda”, which is more alkaline than baking soda, it will be easier to remove stains. Sodium carbonate is also a natural cleaning product, so if you are interested, please try it.

Let’s learn how to remove oil stains and make the ventilation fan last longer.

Ventilation fans are not within easy reach and seem difficult to clean, so they tend to be put off. However, if you get the hang of it, you can remove the dirt efficiently. Keeping the ventilation fan clean while using convenient goods will make you feel better in the kitchen.
