How to Clean Greasy Kitchen Range Hoods
Share
Why Cleaning Your Range Hood Matters
Your kitchen range hood works hard every time you cook — trapping grease, smoke, and odors before they spread through your home. But over time, that grease builds up on the filters, fan blades, and hood surfaces, reducing efficiency and becoming a fire hazard. Regular cleaning keeps your kitchen safer, your air cleaner, and your appliance lasting longer.
What You'll Need
- Dish soap (degreasing formula)
- Baking soda
- White vinegar
- Hot water
- Microfiber cloths or sponges
- Old toothbrush or small scrub brush
- Rubber gloves
Step 1: Remove and Soak the Filters
Most range hoods have mesh or baffle filters that catch the bulk of the grease. Remove them carefully — they usually slide or pop out. Fill your sink with very hot water, add a generous squirt of dish soap and ¼ cup of baking soda, and submerge the filters. Let them soak for 15–30 minutes.
After soaking, scrub with a brush to remove loosened grease, rinse thoroughly, and let them air dry before reinstalling.
Step 2: Clean the Interior Fan and Vents
With the filters removed, you'll have access to the fan blades and interior vents. Spray a mixture of equal parts white vinegar and water onto the surfaces and let it sit for 5 minutes. Wipe down with a microfiber cloth, using an old toothbrush to get into tight corners and around fan blades. Avoid getting moisture into electrical components.
Step 3: Degrease the Exterior Hood Surface
For stainless steel hoods, mix a few drops of dish soap with warm water and wipe down the surface with a microfiber cloth. For stubborn grease spots, apply a paste of baking soda and a little water, let it sit for 5 minutes, then scrub gently and wipe clean.
Always wipe in the direction of the grain on stainless steel to avoid scratching.
Step 4: Tackle the Grease Trap (If Applicable)
Some range hoods have a small grease trap or cup that collects drippings. Empty it, wash it with hot soapy water, and dry it before replacing. This should be done monthly to prevent overflow and odors.
Step 5: Final Wipe-Down and Polish
Once everything is clean and dry, do a final wipe of all surfaces with a clean, dry microfiber cloth. For a streak-free shine on stainless steel, a small amount of mineral oil or baby oil on a cloth works beautifully — it also helps repel future grease buildup.
How Often Should You Clean Your Range Hood?
- Filters: Every 1–3 months depending on cooking frequency
- Exterior surfaces: Weekly wipe-down, deep clean monthly
- Grease trap: Monthly
- Fan blades and interior: Every 3–6 months
Pro Tips for Easier Maintenance
- Run your range hood fan every time you cook — even for quick meals
- Wipe down the exterior with a damp cloth after each cooking session to prevent grease from hardening
- Use a splatter screen on pots and pans to reduce grease output
- Replace charcoal filters (in ductless hoods) every 3–6 months
