How to Clean the Inside of a Kitchen Hood Vent
Grease builds up where you can’t see it — inside the canopy, on the filters, and around the blower. Here is a simple, safe, step-by-step way to clean the inside of your kitchen hood vent, restore airflow, and lower fire risk.
Before you start
What you’ll need
Most of this is already under your sink. Work in good light and give the degreaser time to do the work so you are wiping, not scrubbing.
- Grease-cutting dish soap + baking soda
- Kitchen degreaser spray
- Microfiber cloths + a soft brush
- Hot water and a sink or large bin
- Rubber gloves
- A step stool for high hoods
Step by step
Cleaning the inside of your hood vent
Cut the power
Switch the hood off at the wall switch or unplug it. Never clean fan blades or a blower while the unit can turn on.
Remove the filters
Slide out the baffle or mesh grease filters from the underside of the hood. Most release with a small spring catch or handle.
Soak the filters
Submerge the filters in hot water with a few tablespoons of grease-cutting dish soap and a quarter-cup of baking soda. Let them sit 10–15 minutes, scrub with a soft brush, and rinse.
Degrease the inside of the hood
Spray a kitchen degreaser across the interior canopy and walls, let it dwell 2–3 minutes, then wipe away the softened grease with a microfiber cloth. Repeat on stubborn spots rather than scrubbing hard.
Clean the fan and blower
Wipe the accessible fan blades and blower housing with a degreaser-damp cloth. Keep moisture away from the motor — never soak it.
Wipe the vent opening
Clean the accessible duct collar and vent opening as far up as you can safely reach with a cloth on a flexible handle.
Dry and reassemble
Dry the filters completely and reinstall them in the correct orientation so they seal properly.
Polish the exterior
Finish by cleaning the outside of the hood. On stainless steel, wipe with the grain for a streak-free, fingerprint-free shine.
Keep it up
How often to clean inside a hood vent
Wash the filters every 1–3 months if you cook often. Give the inside of the hood, blower, and accessible vent a deeper clean every 6–12 months — sooner if you fry or sear at high heat. Regular cleaning protects airflow and is one of the simplest ways to lower kitchen fire risk.
- Filters: every 1–3 months
- Inside canopy + blower: every 6–12 months
- After heavy frying: sooner

Questions
Cleaning a kitchen hood vent, answered
How do I clean the inside of a kitchen hood vent?
Turn off the power, remove and soak the grease filters in hot water with dish soap and baking soda, spray the inside of the hood with degreaser and wipe it down, clean the accessible fan and vent opening, then dry and reassemble. Finish by polishing the exterior with the grain.
Can I put my hood filters in the dishwasher?
Mesh and stainless filters usually handle a dishwasher cycle, but aluminum filters can discolor and dull. A hot-water soak with dish soap and baking soda is the safest method for all filter types.
What is the best degreaser for range hood grease?
For routine cleaning, hot water with grease-cutting dish soap and baking soda works well. For heavy, baked-on grease, a dedicated kitchen degreaser is more effective — just match it to your hood’s finish and avoid abrasives on stainless or copper.
How often should I clean inside my hood vent?
Clean the filters every one to three months and deep-clean the inside of the hood, blower, and accessible vent every six to twelve months — more often if you cook at high heat.
