1. Boil a Pot of Water
Start by bringing a large pot of water to a rolling boil. You want enough water to fully submerge your filter. Nana always told me that the hotter the water, the better, so don’t skimp on getting that water nice and hot.
2. Add Baking Soda (Slowly)
Once the water is boiling, slowly add 1/4 to 1/2 cup of baking soda into the pot. Add it gradually to avoid a fizzy mess. The baking soda works as a mild abrasive and natural degreaser, breaking down the stubborn grease without the need for harsh chemicals.
3. Submerge the Greasy Filter
Carefully place your greasy oven hood filter into the pot or basin. If the pot isn’t big enough to fit the whole filter, you can do one side at a time or use a deep sink to hold the boiling water.
4. Let the Filter Soak
Here’s where the magic happens with almost zero effort. Once submerged, the boiling water and baking soda start working to break down the grease. You’ll see the grease lifting off the filter, floating to the top of the water. Let the filter soak for at least 10-15 minutes. For extremely greasy filters, you can leave it longer, but even the worst cases don’t need much scrubbing after this soak.
5. Rinse the Filter
After soaking, carefully remove the filter from the hot water using tongs or gloves to avoid burning yourself. You’ll notice the grease has already dissolved or loosened considerably. Rinse the filter under warm running water to remove any remaining grime. If needed, you can give it a light scrub with a brush or sponge, but in most cases, the water and baking soda solution will have done most of the work.
6. Let It Dry
