A greasy range hood can make your whole kitchen feel sticky, dull, and harder to keep clean. Because it sits right above the stove, it collects a mix of oil, smoke, dust, and cooking residue over time. The good news is that you usually do not need anything fancy to clean it well. Hot water, dish soap, baking soda, vinegar, a microfiber cloth, and a little patience can go a long way. Source Source

Why range hoods get so greasy
Range hoods are designed to pull in airborne grease, smoke, steam, and odors while you cook. That means the filter and underside of the hood are constantly catching residue. If you skip cleaning too long, the filter can clog and the hood may not ventilate as well. Home Depot notes that a dirty filter can reduce proper ventilation, and Martha Stewart highlights that grease buildup can cake onto both the interior vent area and exterior surface. Source Source
7 greasy range hood hacks that make cleaning easier
1. Start with hot water and degreasing dish soap
One of the simplest hacks is also one of the most effective. Home Depot recommends hot water and degreasing dish soap as one of the best DIY degreasers for a range hood. This is a great first step before reaching for stronger products. Source
2. Use a vinegar-and-water spray on the exterior
For sticky grease on the outer hood, Home Depot suggests mixing one part vinegar and one part water in a spray bottle and wiping the surface down with a microfiber cloth or paper towel. It is a simple, low-cost way to loosen oily film. Source
3. Make a baking soda paste for stubborn grime
If sprayed-on cleaner is not enough, both Home Depot and Martha Stewart mention baking soda-based methods. Home Depot suggests a thin paste of warm water and baking soda for tough stains under the hood, while Martha Stewart recommends a homemade paste using equal parts baking soda and water for stubborn grease.

4. Soak the filter instead of attacking it dry
A greasy range hood filter is much easier to clean after soaking. Home Depot recommends filling the sink with hot water, dish soap, and baking soda, then soaking the filter for 15 to 20 minutes before scrubbing. Martha Stewart also recommends soaking filters and grates in warm, soapy water. Source Source

5. Use a non-abrasive brush, not harsh scrubbers
Simple Green recommends using a nylon or non-abrasive brush on metallic range hood filters. Martha Stewart also advises avoiding abrasive sponges and scrubs on sensitive materials like stainless steel. That means gentler tools usually work better than aggressive ones. Source Source
6. Wipe stainless steel with the grain
If your hood is stainless steel, Martha Stewart recommends wiping it with a microfiber towel with the grain. She notes that circular motion can leave scuffs. That small detail can make a big difference in how polished the hood looks afterward. Source
7. Let the filter air-dry completely before reinstalling
Both Home Depot and Simple Green say to let the filter dry completely before putting it back into the hood. Reinstalling a damp filter is not worth the risk of trapping moisture where it should not be. Source Source
Step-by-step: how to clean a greasy range hood
Step 1: Gather your supplies
A practical setup includes:
- hot water
- degreasing dish soap
- baking soda
- vinegar
- microfiber cloths
- a non-abrasive brush
- gloves if the filter is especially grimy Source
Step 2: Wipe down the exterior
Spray the outer hood with either your preferred grease-cutting cleaner or a 1:1 vinegar-water mix, then wipe thoroughly with a microfiber cloth. For stainless steel, wipe with the grain. Source Source
Step 3: Scrub the greasy underside
The underside usually needs more work because it catches oil splatters and smoke. Home Depot recommends using a brush that scrubs without scratching. If grease remains, work in a baking soda paste and wipe away loosened grime with a dry towel. Source
Step 4: Remove and soak the filter
Most hood filters can be removed using a metal loop or latch. Home Depot recommends soaking the filter in hot water, dish soap, and baking soda for 15 to 20 minutes, then scrubbing until the grease loosens. Source
Step 5: Rinse and dry fully
Rinse thoroughly, then let the filter air-dry before reinstalling. Simple Green gives a similar process for metallic filters: spray, brush, let the cleaner sit 3 to 5 minutes, rinse with hot water, and air-dry. Source
How often should you clean it?
Martha Stewart cites expert advice suggesting you clean the range hood and its parts once per month, or every three months if you cook less often. Simple Green notes that many manufacturers recommend cleaning metallic filters at least once a month. Source Source

A few important cautions
Not every filter should be cleaned the same way. Simple Green says:
- metallic filters should be cleaned regularly,
- fabric filters should be replaced rather than cleaned,
- charcoal filters in ductless hoods should also be replaced rather than cleaned. Source
Home Depot also recommends checking the vent or ductwork while cleaning. If you notice serious grease buildup in the vent itself, they advise calling a professional, since heavy vent grease can affect performance and may create a fire risk. Source
Easy weekly routine to keep grease under control
If you want to avoid a big cleanup later, use this simple routine:
- Wipe the exterior weekly with warm water and dish soap or vinegar spray.
- Spot-clean the underside after heavy frying.
- Deep-clean the filter monthly if you cook often.
- Check your hood manual for material-specific care.
- Inspect the vent area occasionally for heavy buildup
