Pull the metal filter out from under your range hood and hold it up to the light. If barely any light comes through, you're holding the most flammable object in your kitchen — a mesh soaked in months of vaporized cooking grease, mounted directly above your burners. That's the honest reason range hoods deserve a deep clean on a schedule: it's less about shine and more about not giving a stovetop flare-up something eager to catch.
The filter: a 20-minute soak does the work
Forget scrubbing cold grease — chemistry first.
- Slide the filter out (most release with a small latch or a push toward the back).
- Fill the sink with the hottest tap water you have, a generous squirt of degreasing dish soap, and a half-cup of baking soda. Stir until it foams.
- Submerge the filter for 15–20 minutes. The grease that laughed at your sponge softens into something a soft brush removes in passes.
- Brush gently along the mesh, rinse hot, and let it dry completely before it goes back — a damp filter grabs new grease twice as fast.
Heavily neglected filters may need a second soak, or a pot of gently simmered water with baking soda for the stubborn crust. If a filter stays opaque after two rounds, replacements cost little — and a fresh filter outperforms a half-cleaned one.
The hood itself: work with the grain
- Exterior: warm soapy water or a degreaser suited to your finish — stainless wants wiping WITH the grain, then a dry-cloth pass to prevent streaks. Skip abrasive pads; they scar stainless permanently.
- Underside and cavity: degreaser on a cloth (never sprayed into the vents where it can reach the motor), working the film off the baffle area and around the light housings.
- Controls and edges: the greasy fingerprints live here — a barely damp microfiber with a drop of dish soap resets them.
Unplug or cut power first if you're working near the fan or bulbs. Water and live sockets don't negotiate.
How often is enough?
For daily cooks — especially high-heat or wok cooking — the filter earns a monthly soak; lighter kitchens can stretch to every two or three months. The hood's exterior joins the regular kitchen wipe-down; the full deep-clean treatment belongs in your seasonal reset. The test never changes: hold the filter to the light.
What a hood clean can't fix
If the fan runs loud, weak, or not at all with a clean filter, the grease has likely reached the blower or the duct — that's appliance service, not cleaning. And per our standing rule of honest expectations: cleaning restores clean, not chrome. Pitted or heat-discolored stainless keeps its scars.
The version where you don't do any of this
Range hoods are exactly the kind of task our kitchen deep cleaning exists for — the degreasing chemistry, the dwell time, and the detail work above the stove, handled in the same visit as the cabinets, backsplash, and appliances. It's a favorite add-on for San Jose clients who cook seriously and would rather not spend a Saturday elbow-deep in grease → Kitchen cleaning service · Kitchen cleaning prices
