Cleaning the kitchen exhaust hood is what everyone needs to have a clean kitchen. We tend to clean and scrub every corner of our kitchen, but what about the parts we cannot see?

Buying any appliance is one thing, but you will not be doing its maintenance as required. It will all be the same no matter how much you have invested.

. Soaking the parts

Now that you have prepared your solution, it’s time to soak the parts of your kitchen hood such as the oily kitchen exhaust fan in the baking soda solution. 

Let them sit in this solution for 15- 20 minutes, depending on the grease and stains stuck on the filters and fans. 

. Brushing off the grease

The baking soda and degreasing soap soften the grease, dirt, and grim. Now, you can easily clean the parts with the least effort. 

Because we want ease at the end of the day, which is what baking soda will do. It will make your job much easier. 

With a soft bristle brush, clean the filters and ducts. The brush will help you reach the areas where you fail to clean.

Do keep in mind not to scrub so hard that it damages the integrity of the parts. 

. Washing with water

All the dirt and unwanted grease are scrubbed and washed to remove any leftover stains. 

. Drying

You might think you are done with scrubbing and washing, and your job is done. But, let me tell you, if you skip this step and assemble your kitchen hood as it is, you might regret it later. 

Remember to dry all the parts to rule out any water stains and rust or corrosion signs. 


  1. This method effectively removes dirt and grease.
  2. It can help combat any foul or unpleasant odor. 
  3. All the ingredients are cheap and available at home. 

Things You Need to Consider 

It might be possible that you are not aware that baking soda is a potent agent. If not used with caution, it will damage more than any good. 

Remember to clean the parts after the baking soda bath, as it might leave a white film and might keep damaging the surface of your kitchen hood.

2- Pressure Washing

The second method for cleaning the kitchen hood is pressure washing. It uses high-pressure water for cleaning any mold, dirt, and mud. 

The forceful water pressure emits any grease and residue. 


Pressure washing your kitchen hood will make it easier to reach inaccessible areas.


It might help in combination with baking soda as that helps alleviate the grease, and then the pressure wash will remove the stuck oil. 

The pressure wash itself is not so good with adhering layers of oil and grease.

The exterior of Your Kitchen hood
