How To Clean Cooker Hood Filters (Remove Tough Grease Easily!)

Are you a whiz in the kitchen? If you’re a foodie and love nothing more than whipping up a gourmet feast, you will know the importance of proper appliance maintenance. Your oven is your best friend. So — if you don’t keep its hood grease-free — you could run into some problems. Luckily, we have the answer for you. This short and sweet guide will look at how to clean cooker hood filters and some handy tips on keeping them clean. 

Why you should clean your cooker hood filters

Before we go any further, let’s take a moment to delve into why you should clean your cooker hood filters. Since the hood sits directly above the stove, all the grease and grime rise up towards it. The main purpose of this filter is to catch all of that. However, there’s one problem, over time, it can build up and become clogged. When that happens, you will find that it doesn’t work as well as it once did and could be a risk.

It can be a real hazard if your cooker hood filter is full of grease. According to a report from the Express newspaper, there are four problems you can expect to see here:

●     Fire risk

If you haven’t cleaned your cooker hood filter in a while, there may be an increased risk of fire in your kitchen. Since the grease is highly flammable, it could set alight if it gets too hot when you are cooking. However, the report notes that you don’t need to use an open flame for this type of problem. Any kind of heat can cause a fire to start.

●     Smoke hazards

It’s not just fires that you need to worry about! You could find that a greasy cooker hood filter can lead to steam and smoking hanging around your kitchen. As you may already know, the whole point of the extractor fan is to prevent this from happening. However, when it is clogged up with grease, it stops being able to do that. To avoid this problem, it is best to learn how to clean cooker hood filters and do it regularly.

●     Mould problems

You cook in your kitchen, so you need it to be as clean as possible. It might be a shock to learn that a grease build-up in your cooker hood filters can lead to bacteria and mould. The moisture in the hood makes for an excellent breeding ground for any type of bacteria. You should clean them often to avoid this issue.

●     Financial issues

Are you trying to watch your pennies? If the answer is yes, it pays to clean your cooker hood filters regularly. When your home gets smoky — as a result of not cleaning your extractor fan — it can damage your ceilings and walls. That means you will have to redecorate your home more often than you might imagine. Fixing those annoying issues will cost you both time and money. So save yourself all that trouble!

How to clean the stove hood extractor fan

Now that you know why you should clean the stove hood extractor fan, let’s delve into how you can get the job done. The good news is that this is much easier than you might imagine. You don’t need to have any technical know-how to get it right. Just gather some things — that you likely already have at home – and follow our simple steps here.

You will need the following:

  • Bucket
  • Soft, dry cloth
  • Hot water
  • Baking soda
  • Soft bristle brush
  • Washing-up liquid
  • Old newspaper

Step 1: Remove the filters

Want to know how to clean an extractor fan? The first thing you need to do — before you get to work — is remove the filters from the extractor fan cooking hood. In most cases, this will be relatively simple. You can slot them out of the cooker hood and bring them down onto the surface. If you have any trouble with this step, you might want to refer back to your oven manual to get a full breakdown of what you need to do to get it right.

Step 2: Fill the bucket up

Next up, you need to fill the bucket with some hot water. Finally, add some washing-up liquid and a teaspoon of baking soda. That makes the perfect cleaning combination for your extra fan filters.

Step 3: Put the filters in the water

When you’ve done all of the above, the next step is to thoroughly submerge the extractor fan filters in the bucket. Make sure every part of the filter is covered. If the pieces don’t quite fit, you might have to do one or two at a time. Alternatively, you could use two buckets.

Step 4: Allow them to soak

Leave the extractor fan filters to soak for around 10 minutes. Then, if you have more time to spare, you can leave them there for 20 minutes. However, you shouldn’t leave them for longer, or you may find that the water starts to damage the metal on the filters.

Step 5: Scrub the filters

The next step means taking the kitchen extractor filters out of the water and scrubbing them. You can use both the soft brush and the cloth for this job. You may want to use the brush to target any of the stains or marks you find on your filters. On the other hand, the cloth is better for more general marks and can be used all over them.

Step 6: Leave the filters to dry

Lay out some old newspaper on the side and put down each filter. You want to ensure that each kitchen extractor panel is completely dry before you put everything back together. Ideally, you will need to leave the filters for around an hour.

Step 7: Put the extractor fan back together

The final thing you need to do here is put the extractor fan back together. Again, you should follow the instructions that you can find in your oven manual to get this right. The whole job should take you around five minutes to complete!
