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, and 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
