Kitchen Chimney Cleaning Easily At Home?

Kitchen chimney cleaning is a very difficult and time-consuming task. Most of our Indian dishes contain a lot of spices and oils that produce a lot of smoke. A kitchen chimney is helpful for extracting the steam and smoke generated during cooking. The oil and fat in the smoke can get stuck between the filters, which can affect the efficiency of the fireplace.

Occasional cleaning not only keeps the chimney clean, but it also improves its efficiency. Nowadays, manufacturers also develop self-cleaning chimneys. If you don’t have a lot of time to clean, they are the perfect solution for you. However, they are much more expensive.

If you have a kitchen chimney to clean manually and are wondering how to keep it clean, read the following instructions carefully. It contains step-by-step instructions for cleaning and maintaining a kitchen chimney with natural ingredients that are easily available in every household.

Some of the natural ingredients that help clean a kitchen chimney are caustic soda, vinegar, dish soap, salt, and others. Below we have listed methods for the individual use of these ingredients.

1. Detergent

Liquid dishwashers are readily available in every household. The liquid surfactants contained in the detergent easily dissolve and remove the fat and oil deposits.

Step by step:

  • Carefully remove the filters in the chimney.
  • Apply a little washing-up liquid to the filters with a sponge.
  • Now fill a bucket with hot water.
  • Insert the filters completely into the water bucket.
  • Let rest for 1 – 2 hours.
  • Now remove them from the water and scrub them gently with a non-abrasive washer.
  • Wash with clear water and allow to dry completely.

2. Hot water

This is one of the easiest ways to clean a kitchen chimney filter. It’s perfect for people who don’t have much time for the cleaning process. The boiling water unlocks the grease and oil stains on the filters.

  • If you have a large steel container.
  • Insert the filters and add water until the filters are fully immersed.
  • Cook for 30 minutes on a slow flame.
  • Turn off the oven and carefully remove the filters.
  • Wash with normal water.
  • Wipe them with a dry cloth.
  • Dry them completely before placing them in the kitchen fireplace.

3. Baking soda

Baking soda is the most common ingredient in every household. And it is also recognized as an all-purpose cleaning solution. The mild alkaline and abrasive properties of baking soda easily break down fat and oil without causing damage.

  • Take a large tub and filter it with hot water (boiling temperature).
  • Add 2-3 tablespoons of baking soda, 2 cups of vinegar and 2-3 tablespoons of salt.
  • Immerse the filters in this solution for 1-2 hours.
  • Now remove the filters from the water and scrub them carefully with a mild washer.
  • Wash with clear water and dry completely before replacing them.

4. Paint thinner

Due to its ability to easily remove stubborn grease and oil stains, the paint thinner is perfect for cleaning kitchen fireplaces. If you don’t have a paint thinner at home, you can use nail polish instead.

  • Take a piece of cotton cloth.
  • Dip this cloth in paint thinner or nail polish.
  • Gently scrub the filters to remove grease and oil.
  • After scrubbing, wash the filters thoroughly in clear water.
  • Put them in the sunlight to dry them naturally.

5. Vinegar

Like baking powder, vinegar is available in all households and is also considered an all-purpose cleaner. In addition to the acidic and mild abrasive properties, vinegar also has disinfectant properties so that no germs can occur.

  • Take a small tub of hot boiling water.
  • Add 1-2 cups of vinegar and mix well.
  • Now immerse the chimney filter in this solution.
  • Let rest for 1 – 2 hours.
  • Now scrub the filters with a non-abrasive washer.
  • Wipe with a damp cloth.
  • Let it dry completely before putting it back.

6. Caustic soda

If none of the above ingredients worked or if the grease and oil stains are too stubborn, this is the perfect solution. The acidic nature of caustic soda easily removes the grease or oil stains.

  • Remove the filters from the chimney and place them on a tray.
  • Sprinkle some caustic soda over the filters.
  • Pour boiling water over them.
  • As soon as you do this, vapours will come out.
  • Leave on for 2-3 hours without disturbing it.
  • Scrub them carefully and wash them with clear water.
  • Dry them carefully before putting them back.

Points to note: Do not touch caustic soda with your bare hands as this can cause burns. It is better to wear protective clothing while following this procedure.

How often should we clean kitchen chimney filters?

The answer to this question depends on the use and type of the kitchen fireplace. If you use the chimney very often or cook a lot for many people, you will need to use it frequently. If you do not search often or do not use the chimney regularly, you can clean it occasionally.

However, the frequency of cleaning also depends on the type of filter in the chimney. Below is the average cleaning time required for each filter.

Cassette Filters – These filters consist of multilayer aluminium layers. Since these filters contain small pores, glue and block them. It is therefore important to clean them once every 8-10 days.

Impact filter – These filters have the technology to separate smoke and fat. You won’t get constipated regularly. So clean them once every 2-3 weeks.

Carbon filter – The charcoal granules contained in it absorb smoke, odour, and fat. They cannot be cleaned and should, therefore, be replaced every 3 to 6 months.

Is it really easy to maintain chimneys with automatic cleaning?

Some of the modern kitchen chimneys are equipped with automatic cleaning, which makes the entire maintenance process very simple and straightforward. All you have to do is click a button – a heating element in the fireplaces breaks down the fat and sends it to an oil collection box. Now and then you can simply remove the collector and clean it thoroughly.


Many of our Indian dishes produce smoke, which causes too much dirt and fat to accumulate in the chimney in the kitchen. The fat and oil deposits can block the filters and reduce the suction power, which ultimately reduces the efficiency of a kitchen fireplace. Cleanliness is therefore one of the most important things to keep the chimney working for a long time.

Most people believe that cleaning the extractor hood is not an easy task. But that’s not true. It just takes some time and patience. You don’t need professional help for this. We have mentioned some procedures above for your convenience. All of these processes use only natural ingredients that are readily available in your kitchen.
