How to Clean a Greasy Overhead/Range Hood Exhaust Filter the Easy Way

Sharing is caring!

This is a highly overlooked item in your home that probably doesn’t get cleaned as often as it should. I didn’t really give my range hood filter much thought before I started cleaning my home on a regular basis.

Most of you will probably never look under your range hood unless the light bulb goes out. Don’t feel bad, that’s pretty much how I found all that disgusting dirt that grossed me right out. Once I noticed the grime, it stuck out like a sore thumb and I had to find an easy and effective way to get the grease range hood clean.

The main thing that really grossed me out was the fact that if I was boiling water in an open pot, and some of that grease was to melt off, it would plop right into my pot of water where I was most likely cooking something delicious…and ruin my whole meal.

Not to mention the effectiveness of the filter is affected if too much buildup is an issue.

So yeah, I’m not a fan of the grimy, greasy overhead exhaust filter, and I clean mine when it gets super built up which is usually every few months.

I did a little digging around for a good cleaning hack for cleaning that greasy range hood, and while I did come across some good ideas, I found most of the ideas I found, didn’t actually work all that well. I was always stuck with a little bit of grease and grime.

The most effective strategy that worked for me was good old baking soda, hot water, and dish soap.

How To Clean Your Range Hood Filter

Materials Needed

  • Baking Soda
  • Dish Soap
  • Hot Water (Boiling)
  • Sink or large pot


If you’re using a pot, grab a large pot that accommodates at least half of your filter. If you’re going to use your sink, plug it up with a sink plug and add some boiling hot water to it, enough to submerge your filter.

Add in 1/2 cup of baking soda a little bit at a time and watch the water fizz.

Submerge your filter into the water. If you’re using a pot, you’ll likely only fit half the filter, so you’ll have to do this process once more for the other half of the filter.

Let the filter soak for a few minutes and watch some of the initial grease floats right off the filter. Gross, yet super satisfying!

Check your filter out, and see if it’s clean and shiny.

If there is still grease on the filter, grab your trusty dish soap ( I love blue dawn)

Add a few drops of dish soap into your water and let the filter soak for another 30 minutes. If needed, you can lightly scrub the filter with a sponge or a soft scrub brush.

When you’re finished waiting for the 30 minutes, pull out the filter and rinse it off until the water runs clear.

Your filter should be sparkling by now.

Make sure you dry off the filter for a few hours before plopping it back into your range hood and you’re good to go!

If you’re super eager, you should probably repeat this process once a month, but if you’re a busy mom like me and can get it cleaned once every few months, that’s fine too!

Don’t forget to clean the drywall and tile around your range hood too.

Still old, but it’s much cleaner!
