I have Spring cleaning fever really bad this year. I've been cleaning everything I can get my hands on. My greasy hood vents drive me crazy. I wash them under hot water and put them in the dishwasher but they just never get as clean as I would like. Recently, I saw this tip and my problem is now solved.
All you do is bring a deep pot of water to a boil. Place the filter in the boiling water. Slowly, add 1/2 cup of baking soda. Do this slowly as the water will bubble ferociously.
The water almost instantly starts to look like gross sludge.
Turn your filter over to get both sides. Once they looked clean, I ran them through the dishwasher for good measure.
Perfectly clean. I love it when I find good tips like this! Just throw the gross water down your sink and run hot water to wash it down.
