How to clean kitchen chimney? A simple guide with photos.

Kitchen chimneys are a vital appliance for keeping the kitchen free of smoke, grease, and odor. With filterless and auto-clean chimneys entering the market, the cleaning process has become easier. You still are required to get your hands dirty, but it is relatively an easier job than you think.

Cleaning is also a part of maintenance. And maintaining an appliance sure increases its life and makes sure that it works at its peak. So, buckle up and put on your apron, and follow these steps to clean your kitchen chimney inside-out.

Things you need for cleaning the kitchen chimney

As this is about cleaning the chimney at home, I’ll be using all the things that are available in all kitchens. And this simple list should help you with it.

  • Paper Towels (newspaper would do, too)
  • Dishwashing soap
  • An old toothbrush
  • A tub for the filter to be cleaned
  • Hot water
  • A dry rag

And that’s all you need. Now, let’s get started.

Steps for cleaning the Filter

Since chimney cleaning involves cleaning the interiors and the exteriors, you can navigate through the article using the headings. This one is for the filter.

Step 1 – Use a paper towel for freshly settled oil

Taking out the grease at the surface is the first thing you do. Simply take a piece of paper towel and wipe the chimney filter with it. The fresh (loose) grease and oil on the surface can be cleaned like this.

Step 2 – Mix boiled water and dishwashing soap in a tub

Depending on the size of the tub and the filter, take an adequate amount of water and add dishwashing soap just to make enough bubbles.

Tip – Use a toothbrush for mixing the dishwashing soap as the water is hot.

Step 3 – Soak the chimney’s filter

Unscrew the bolts and take the chimney’s filter out. Place it in the tub and let it soak in the solution for at least 10 minutes. The solution will de-grease the filter’s surface and make it ready for next step of agitating.

Step 4 – Agitate with toothbrush

Since we have used dishwashing soap in the water, agitating the already suspended grease becomes really easy. Now, brush along the filter channels with light force. Do this on all the channels.

Step 5 – Rinse under running water and wipe with a dry cloth

Take the filter and place it under running water. This should clean all the dirt that you’ve agitated in the last step.

Rinse off the dirt from the filter

Post rinsing the filter, do NOT put it back in the chimney yet. Wipe it dry with a cloth and let it sit for a minute or two.

Step 6 -Look at the cleanliness and drool

Yes, that sums it up. A clean, non-greasy filter is something you should be drooling over!

Steps for cleaning the oil collector

Not all chimneys have this little oil collector. But for those that have them, cleaning them is as easy as cleaning an oil-drenched plate after eating pav-bhaji!

Step 1 – Drain the excess oil

There is no point in carrying the excess oil and soaking the toothbrush in it for cleaning. So, drain the excess oil in the sink while running the tap.

Step 2 – Soak it in hot water and dishwashing soap

Killing the grease is easier when it is suspended in hot water and dishwashing soap solution. The acid in the dishwashing soap helps the process speed up. Let it rest for 10 minutes and get ready with a toothbrush for the next step.

Step 3 – Brush in circular motion

Now, after you see the suspended oil and grease, it is time to brush them off clean. Take an old toothbrush and start with one end. Lightly brush in circular motion end-to-end 2-3 times. Doing it repeatedly for 2-3 times ensures the coverage of the maximum area. It should leave you with a foggy residual water in the oil collector.

Step 4 – Rinse under running water and wipe dry

Now, all you are left with is draining the dirty foggy water and rinsing the oil collector with running water. It should be enough to clean the major oil deposits. If you still feel some oiliness, take a sponge scrub, slap some dishwashing soap and scrub it off.

Step 5 – Dry and assemble

You are at the finish line, people. Just put it back after you wipe it dry with a cloth. You have, now a clean oil collector.

Cleaning the interiors of the chimney

This is the easiest of all. It goes without saying that cleaning the extra oil with paper towel is the way to go. So, take a piece of paper towel and wipe clean the oil deposits.

If the oil is too stubborn, you can make a thick paste using 3 parts baking soda and 1 part water. Now, apply this paste using a toothbrush to the stubborn oil deposit area and let it dry for half an hour. Clean it off using a paper towel or any rag.


Cleaning the chimney or any kitchen appliance is easy as long as you know what to use when. I am sure that you are now confident in cleaning the chimney all by yourself.

A lot of times the internet misguides you with weird chemicals that are being sold at Amazon. Not only these chemicals can be dangerous for you, it can ruin the materials used in making your precious kitchen appliance.

So, try to use basic natural (or non-harmful) agents whenever it is possible. For example, use a mixture of vinegar and water to wipe clean the mirror rather than using Colin. It is easy and won’t make you breathe funny!

Be natural, stay raw.
