The filters in your oven vents may not be something you need to clean regularly, but when you do, it's a hassle. You can simplify the process with a little bicarb soda and water.
As homemaking blog The Manly Housekeeper points out, you can de-grossify your oven vent filters by placing them in a large pot of boiling water with about half a cup of bicarb soda:
This had potential. I brought a large pot of water to a boil, added the bicarb soda (slowly, so it didn't fizz all over the place) and dropped the filters in. Five minutes later I poured out the water.
What did I find? Much cleaner vents and a horrible grease ring around the rim of my pot.
The resulting ring of grease around the rim of the pot you used should be easily cleaned up with regular detergent. Just be sure to find a safe place to dispose of the dirty water. Oh, and mind the smell.
