How to Clean a Greasy Range Hood Filter

How to Clean a Greasy Range Hood Filter

Your range hood filter does a tough job—trapping grease, smoke, and grime to keep your kitchen air clean. But if it’s been a while since you cleaned it, it’s probably clogged with grease and not working as efficiently as it should. The Trade Table will walk you through it.

How Often Should You Clean It?

✔️ Every 2-3 months for regular cooking.

✔️ Monthly if you fry foods or use a wok often.

✔️ Right after heavy cooking sessions (holidays, big dinner parties).

✔️ If your range hood  data-end="584" data-start="555">isn’t clearing smoke well or has gotten extra loud, it’s time for a cleaning!

How to Clean a Greasy Range Hood Filter (Step-by-Step Guide!)

This easy method requires no scrubbing—just boiling water, baking soda, and dish soap to dissolve the grease.

What You’ll Need

✅ Very hot or boiling water (the hotter, the better!)
✅ Degreasing dish soap (Dawn works great)
✅ ¼ cup baking soda
✅ Non-abrasive scrub brush
✅ Paper towels or clean dish cloths

Step 1: Remove the Filter

Most range hood filters slide or pop out easily. Look for a metal loop or latch and gently pull it out.

Step 2: Fill a Sink with Boiling Water

The hotter the water, the better it will cut through grease!

If your tap water isn’t hot enough, boil some in a kettle and pour it into a plugged sink.

Step 3: Add Baking Soda & Dish Soap

✔️ Squeeze in a generous amount of dish soap.

✔️ Sprinkle in ¼ cup of baking soda.

✔️ Swish the water around to mix (use a brush, not your hand—it’s hot!).

Step 4: Soak the Greasy Filters

Submerge the filters completely in the hot water.

Let them soak for 10-15 minutes to loosen built-up grease.

Step 5: Scrub the Filters

Use a non-abrasive brush to gently scrub away any remaining grease.

If the grease is stubborn, add more dish soap and scrub again.

Step 6: Rinse & Dry

Rinse thoroughly with hot water to remove all soap and grease.

Dry with a paper towel or clean cloth before reinstalling.

Step 7: Replace & Repeat as Needed

Slide the clean filter back into the hood and repeat this process every few months!

Can You Clean Range Hood Filters in the Dishwasher?

Some metal mesh filters are dishwasher-safe! But if your filter is super greasy, wash it by hand first—you don’t want all that grease clogging your dishwasher!
