When was the last time you took a look under your stove’s hood filter and checked out the range hood filter? I bet that it’s been awhile since…you’ve never done this! And let me tell you something: you won’t gonna like what it’s in there. The main purpose of a hood filter is to collect grease and needs to be cleaned frequently. Otherwise, your hood filter will become blocked with grease and it will be covered with some disgusting sticky film.

If you’ve never cleaned your stove hood filters before, you’ll want to start with a deep cleaning then clean them weekly to keep them in good condition.

You’ll Need:

  • 1/4 cup of Borax
  • Hot Water
  • Gloves
  • Paper towels
  • Sink or large plastic tub


1. Add borax and fill the sink half of water or plastic tub with hot water.
2. Add greasy hood vent filter and soak for 15 minutes.
3. Using the gloves to remove them from dirty water.
4. If hood vent filters are extremely dirty repeat step 1 and 2. After 15 minutes use a gloved hand and swish filter around in borax water to break up any remaining grease.
5. Use a paper towel to wipe off any remaining grease around edges and rinse hood vent filters using clean water.
6. Clean borax hot water mixture can be used to clean underside of hood vent. Make sure to wear gloves to avoid irritating skin.

Another effective alternative would be vinegar and baking soda. These two incredible grease melters will un-stuck dirt from your hood filters.

  • Find a pot large enough for the filter and sufficiently fill it up with water.
  • Bring the water to boil.
  • Once boiling add 3 tablespoons of vinegar and 2 teaspoons of baking soda to the solution, one after another. Add the baking soda in slowly and not all in one go.
  • Place the filter and let it stay for 30 minutes to an hour.
  • Remove the filter using tongs and place it in the sink and scrub hard on both sides.
