The other day I looked at the bottom of my over-the-range microwave and was absolutely disgusted by the condition of the grease filter, which was all clogged up!
I have no idea the last time it was cleaned or replaced, but it was definitely long overdue.
Make your grease filter look like new again
To keep the exhaust fan working efficiently, the manufacturer of my microwave recommends cleaning the grease filter monthly with soap and water.
That sounds so easy, but unfortunately, it didn’t work in this case.
I thought about ordering a replacement grease filter right away, but then I decided to use a different cleaning method -- and this time it did the trick!
Follow these steps to clean your grease filter:
1. Unplug your appliance and remove the grease filter. You may want to use rubber gloves to avoid getting grease on your hands.
2. Bring water to a boil in a large pot or pan. Slowly add about half a cup of baking soda and a few teaspoons of dish soap.
3. Place half of the grease filter into the pot or pan and watch as the grease immediately bubbles up!
4. After a few minutes, you'll see how the baking soda and dish soap begin to tackle the grease. Add more baking soda by the teaspoon if you need to.
5. Once the first side looks clean, flip over the grease filter and get to work on the other half. Notice the difference in the color of the water.
6. After about 15 minutes, remove the grease filter from the water. Touch up any spots with an old toothbrush. Give it a good rinse and let it dry before putting it back.
Even though I have an over-the-range microwave, you could use this same method to clean the grease filter if you have a normal range hood.
The dishwasher might also work, but check your manufacturer's cleaning instructions first.
