How Do I Remove Grease Build-Up from Range Hoods?

The Grease Magnet in Your Kitchen

Your range hood works hard to ventilate smoke, steam, and grease while you cook, but over time, grease and grime build up on the filter, fan, and hood surface, reducing its efficiency and fire safety. A clogged range hood can also spread grease and odors throughout your kitchen, making it harder to keep clean.

In this guide, we’ll show you how to remove grease buildup from your range hood using simple, effective methods—no harsh chemicals required.

Why Clean Your Range Hood?

Improves airflow (prevents smoke and odors from lingering in your kitchen).
Reduces fire risk (grease is highly flammable).
Extends the life of your hood (prevents motor strain and damage).
Keeps your kitchen cleaner (less grease settling on cabinets and walls).

Step-by-Step Guide to Cleaning Your Range Hood

1. Gather Your Supplies

• Dish soap (e.g., Dawn, which cuts grease effectively)

• Baking soda

• White vinegar

• Hot water

• Microfiber cloths or sponges

• Scrub brush or old toothbrush (for stubborn grease)

• Screwdriver (to remove filters and covers)

• Plastic bag or newspaper (to protect countertops)

2. Remove and Clean the Grease Filters

Most range hoods have removable metal or charcoal filters that trap grease and odors. These should be cleaned every 1-2 months (or more often for heavy use).

For Metal Filters:

1. Remove the filters (check your hood’s manual for instructions).

2. Soak in hot, soapy water for 15-30 minutes to loosen grease.

3. Scrub with a sponge or brush to remove stubborn grease.

4. Rinse and dry thoroughly before reinserting.

For Charcoal Filters:

• Charcoal filters cannot be cleaned—they must be replaced every 3-6 months (or as recommended by the manufacturer).

Pro Tip: For extra greasy filters, sprinkle baking soda on them before soaking to boost grease-cutting power.

3. Clean the Hood Interior and Exterior

1. Wipe down the hood exterior with a damp microfiber cloth and mild dish soap to remove surface grease.

2. For stubborn grease, make a paste of baking soda and water, apply it to the greasy areas, and let it sit for 10-15 minutes before scrubbing.

3. Clean the fan and motor (if accessible) with a damp cloth (avoid getting electrical components wet).

4. Use a toothbrush to clean hard-to-reach areas (e.g., around buttons or vents).

4. Clean the Duct (If Accessible)

If your range hood vents outside, the duct can also accumulate grease and dust.

1. Disconnect the duct (if possible) and vacuum out debris with a hose attachment.

2. Use a flexible brush to scrub inside the duct.

3. Reconnect the duct and ensure it’s secure and free of obstructions.

If the duct is not accessible, consider hiring a professional duct cleaning service.

Preventing Future Grease Buildup

Wipe the hood and filters monthly to prevent grease accumulation.
Use the hood every time you cook (even for small meals) to reduce grease buildup.
Avoid frying without a splatter screen (grease splatters contribute to buildup).
Install a grease trap (if your hood doesn’t have one) to catch excess grease.
Check and replace charcoal filters regularly (if applicable).
