It’s no surprise that the chimney filters in India are prone to being so oily and greasy. Most Indian cuisines use a fair amount of spices, oils, ghee and more in their recipes. While that goes on to enhance the taste of the dishes, they’re not friendly with the chimney filters. 

The ingredients used gives rise to a lot of smoke, which leaves residue in the filters. They keep on accumulating in the form of sticky grease. We have to remove this grease periodically and clean the chimney filters 

The importance of periodic chimney filter cleaning 

You may be wondering why at all is it important to clean your kitchen chimneys. It is not only necessary to clean chimney filter to make sure that the chimney functions properly, but also because dirty chimneys run several health hazards. 

All the dirt, oil and grease decrease the efficiency of your chimney. That, in turn, leads to an appliance becoming defunct, and also a dirtier, smoke-filled kitchen. 

If the filter is not clean, then the grease will accumulate over time, until one day it starts dropping onto the surface below. Since, in most likelihood, that’s your gas, the oil droplets falling on an open flame, can even cause a fire in the kitchen. 

These residues on the filters are remnants of several days of smoke and polluted air that couldn’t pass through. If these fall in your food, they potentially contaminate it and make it unhealthy for consumption. 

With the chimney often being a big visible part of your kitchen, dirty chimneys convey a bad message to guests. It not only looks pretty bad but also gives off the wrong vibe. 

Especially with mesh filters, cleaning regularly is important, as otherwise, you’ll have to go through the ordeal of replacing it completely.

Most people tend to resort o hiring professional cleaning services, but we say that you can do it all by yourself too. 

Professional chimney cleaning services vs Cleaning it yourself 

Professional chimney cleaning services in India charge anything between Rs. 1200 to Rs. 2000 for their yearly services, which involve four rounds of cleaning. One-time charges are usually around Rs. 600 to Rs 800. This makes it quite an expensive affair. 

Given the Covid times, it might not be the safest to let strangers enter your place. In cases of lockdowns or curfews, you will be cooking at home yourself, so equipping yourself with chimney cleaning skills might be a very good idea. 

Lastly, professional chimney cleaning services will come once in four months, with them having set periods between two sessions. You and your household needs might be different. Ultimately, how dirty a chimney gets is directly related to how much cooking happens in the house and that is a relative measure for all households. 

Hence, knowing the easy methods of cleaning a chimney filter at home can be of great use. 

How to clean grease from a chimney filter easily 

Some tips and tricks can save you from scrubbing and scratching for hours while trying to rub off sticky stains and oily grease from your chimneys. We’ve listed the top ways to clean your chimney filters at home. 

1. A kitchen dishwasher 

Your regular dishwashing gels, especially the lemon dishwashing gels, can help you immensely while cleaning chimney filters. 

Dishwashing gels are most commonly available and you probably already have some in your house. 

First, take off the filters from the chimney hood and place them in hot water. Then add the gel to that water itself and let the filters soak in the solution for a couple of hours. After doing this, scrub off the grease with a scrubber. Then wash again with normal plain water. Remember to dry it completely before inserting back into the hood. 

Liquid surfactants present in common dishwashing gels help in cleaning grease easily. Another way to apply the same method is to put the gel on the filter mesh directly and then soaking them in the hot water. The results obtained will be the same.

  • Not the most effective for tough stains.

This is a potent cleaning agent, but also a risky one that you have to handle with caution. You can buy it online or at any chemical manufacturing store near you. It’s inexpensive but very useful for cleaning tough stains on chimney filters. 

You must wear gloves while dealing with this substance, so make sure you have those on when you take out the chimney filters to clean them. Put the filters on a tray or flat tumbler and sprinkle some caustic soda on its surface. You might get chemical burns if you touch this substance with your bare fingers, so please remember to wear gloves at all times. After you’ve put the caustic soda on the filters, pour some boiling water over it while standing at a distance. The distance is essential to ensure that the spluttering or fumes don’t harm you in any way. After that, let the tray be like that for about 3 hours. After that take out the filters (while wearing the gloves) and wash them in normal clean water. Then dry it well.

Paint thinners are something you will find easily in any hardware or industrial paint shop near you. These are liquids that are used to dilute the consistency of a paint that has gone dry. Paint thinners are known to contain substances like toluene, acetone and turpentine that help in cleaning stubborn grease from chimney filters. 

All you’ll need to do is dip a clean cloth in paint thinner and wipe the filter. The oils and grease are likely to come off very easily. Paint thinners work by breaking up the particles in oil and grease and thus making it easier to wipe off.

Secondly, while cleaning chimney filters are of utmost importance, remember to clean the inside of your chimneys at least once a year. They too accumulate grease and residue over time, although it’s much lesser in comparison to the filters. For this process, you will need to ask for help from professionals. They’ll disassemble the chimney, the motor and filter to clean it thoroughly. Don’t try the above procedures for the entire chimney.
