Steps to Cleaning Kitchen Exhaust Fan

What most people do when it comes to cleaning their kitchen exhaust fan is they will call an expert to do the job. But the thing is you can do the cleaning if you know the exact steps to follow.

If you don’t have any idea of what steps to follow, no worries. We’ll walk you through it.

The first thing to do in cleaning the kitchen exhaust fan is to remove the grease filter. Turn off your exhaust fan and unplug it from the circuit. This protects you in many ways.

Even if the electricity surges, you wouldn’t be in any danger when you have already unplugged the fan from the circuit. After making sure that you’ve unplugged everything, the next step to do is to remove the grease filter carefully. Kindly make sure to put on gloves for both hands when you do that.

You should see a rectangular, metal mesh section on the backside of the fan. So in order to remove the filter, just loosen any leavers or tabs that are holding the filter in place. Once you’ve finished that, try to pull out the filter gently.

If it doesn’t come out easily, you can use a butter knife and slide around the edges to make the process easier.

After successfully removing the grease filter, keep it in a large pan or container gently. Just make sure that you choose a container that is large and deep enough to hold the filter fully into it. You should understand that once you start cleaning the filter, the container will invariably get dirty. So choosing a plastic bin would be ideal.

The Cleaning Process

After you’ve chosen the container and placed the grease filter into it, it’s time to put together a kitchen exhaust cleaning solution. Actually, preparing it is very simple.

Mix baking soda and dish soap together in a water pot and boil it. These two ingredients are very powerful in removing grease and they are non-toxic in nature. So when you mix them together, you don’t have to worry about inhaling unhealthy chemicals.

Now that the cleaning solution is ready, it’s time that we clean the filter. Take a measuring cup and fill it to the brim with the cleaning solution. Pour it inside the container or the pan that holds the filter.

Continue the cleaning solution one cup at a time until it reaches the top of the filter. When the filter is covered fully with the cleaning solution, leave it alone for 15 to 30 minutes. This’ll give the solution a chance to remove as much grease and grime as possible.

Once the time is up, you can start scrubbing the filter with a sponge or a bristle brush carefully and gently. The grease will come off easily. If it isn’t coming off as expected, then you can let the filter sit in the solution a little longer.

After cleaning the filter fully, rinse it with hot water to get rid of any grease residue or cleaning solution.

Allow it to Dry

After you’ve completely cleaned and rinsed the filter, set it on a cloth towel and let it air dry at least for two hours. It is critical to ensure that all moisture has been removed and dried out before putting back the filter into the exhaust fan.

Number 1, this needs to be done carefully due to safety reasons and number 2, the leftover moisture can cause unnecessary electrical issues.

Clean the Exhaust Fan

While the filter is drying, you can actually go for cleaning the exhaust fan itself. You can use a damp sponge or cloth to remove the grease stain. Avoid flushing chemicals onto the fan directly.

There is a high chance that it will cause an electric issue and if it happens, your fan’s internal components will be damaged and it’ll severely affect its lifespan.

Kindly make sure to wipe out as much grease as possible, and do it even for the fan blades. When you don’t clean the blades, it’ll lead to residual grease buildup and it’ll eventually require more frequent cleaning.

Put the Filter Back in its Place

Once you’ve finished cleaning both the filter and the kitchen exhaust fan, insert the filter back in its place. Put it back exactly like how you removed it and ensure that the leavers and the tabs are tightened properly.

After making sure that everything is perfect, you can plug back the kitchen exhaust fan and start using it normally.
