How to clean a greasy range hood and its filter

Pop the mesh filter out of the hood, lay it in the sink, and cover it with boiling water, a long squeeze of dish soap and half a cup of baking soda. Ten minutes later the grease lets go and rinses away, no scrubbing. Then wipe the hood shell down with warm soapy water — never an abrasive on stainless.

Why the soak does the work for you

Cooking grease isn’t dirt. It’s fat that cooled and set, and cold fat doesn’t dissolve in anything under your sink — which is why dry scrubbing feels like sanding. Boiling water turns it liquid again; dish soap surrounds the droplets so water can carry them off — dish soap is a degreaser by trade, the same reason it’s the first tool on sticky cabinet fronts — and the baking soda pushes the water to the alkaline side, which is where set fat gives up. It’s the same principle behind the baking-soda paste inside an oven, except here you don’t need a paste at all: the part fits in a sink.

The whole sequence, at the sink:

• Turn the hood off and let the range cool. The filter releases on a spring clip or a tab on its front edge: push back, drop the edge, and it comes free. One part, no tools.
• Plug the drain and boil a full kettle. Enough boiling water to cover the part completely, a long squeeze of dish soap, half a cup of baking soda. It will fizz; that’s expected.
• Lay it flat, fully submerged. Ten minutes, untouched. If the water goes orange and cools early, drain and repeat — a filter that has been up there a year almost always wants two soaks.
• Brush gently, along the mesh. A dish brush or an old toothbrush, following the direction of the honeycomb rather than across it: aluminum mesh crushes with less force than you’d think, and crushed mesh doesn’t filter the same.
• Rinse hot and dry it completely. Shake it out, towel it, and let it air-dry before it goes back up. A damp filter grabs the next oil vapor immediately, and you don’t want water going back into the housing the fan lives in.

The dishwasher shortcut most people never try

Most metal mesh filters go straight into the dishwasher, and hardly anyone tries it. Lay it flat on the bottom rack — it rarely fits the top — run the hottest cycle, and run it alone: a saturated filter releases real grease during the cycle, and that grease redeposits on whatever is in there with it. It comes out essentially finished, and the time it saves is sink time.

Two honest cautions. Repeated hot detergent cycles can dull or chalk raw aluminum over time — cosmetic rather than functional, but worth knowing before you make it a monthly habit. And some manufacturers specify hand-washing only; the manual outranks any advice on the internet, this page included. What never goes in the dishwasher is a charcoal filter, and that distinction deserves its own section.

Two filters, two answers — and Miami is full of the second kind

A hood that vents outside pushes air up a duct and out of the building; its only filter is the metal mesh, and that one gets washed for life. A hood that recirculates — ductless — pulls air through the mesh, then through a charcoal filter that holds the odor, and returns it to the kitchen. That charcoal filter is not washable: washing ruins it. It gets replaced, on whatever schedule your model’s manufacturer publishes.

This is the local part the national how-tos miss. In a great many Miami tower apartments — Brickell, Sunny Isles, Miami Beach — the hood does not vent outside at all; it recirculates. So if your mesh came out spotless and the kitchen still smells like last night’s frying, the soak didn’t fail: the charcoal is spent and wants replacing. And if you have never seen a charcoal filter in your own hood, it’s worth a look — many owners have never checked which of the two they have.

The shell: warm soapy water and nothing clever

The thickest film isn’t on the front you look at — it’s underneath: the canopy’s inner face, directly over the burners, takes the oil vapor head on. Start there with a microfiber cloth wrung out in warm water and dish soap, work the front next, and finish with the bottom lip, where the drips gather. On brushed stainless, wipe with the grain and dry immediately so it doesn’t streak. The light lens usually pops out by hand and can go into the sink with the filter.

What should never touch a steel hood: abrasive pads and powders, which scratch the grain permanently and leave a patch that never looks right again; oven cleaner, which is caustic and made for the enamel inside an oven, not for an appliance face; and a melamine eraser, which lifts grease by micro-sanding — the same problem it has on a glossy cabinet door. If soap isn’t winning, the answer is more heat and a longer soak on the part you can soak, not a harsher product on the part you can’t.

When the answer is replace, not clean

Some filters don’t come back. If the honeycomb has closed — dark, stiff, no light through it when you hold it up — after years of never coming down, two soaks will not rescue it, and pushing harder with a brush just crushes the mesh. A replacement is inexpensive and is chosen by model number or by measuring the opening. Replacing it isn’t giving up; it’s the correct repair.

It’s worth saying what that mesh is for, because it reorders the priority of the chore: it exists to catch grease before it reaches the duct and the fan. A blocked filter does two things at once — it stops moving air, so odor and steam stay in the kitchen, and it holds a lot of fuel a few inches above a lit burner. That is why your hood’s manual asks you to wash it on a schedule. It isn’t a dramatic warning; it’s maintenance, like the filter in your air handler.

Where this lands in a JAS visit

The outside of the hood is ordinary kitchen work: the published Standard scope in the booking flow reads “Kitchen surfaces, sink & appliance exteriors,” and a deep clean adds its own line, “Microwave inside & out; stovetop degreasing” — a 4–6 hour visit with a 2-person team, 42 items verified by photo, starting at $349. The full checklist, group by group, is in what a deep house cleaning includes.

Now the honest part, the part almost nobody writes down: pulling the mesh filter and soaking it appears on no published checklist row and no published add-on line. If you want it taken down and soaked during the visit, ask for it in writing when you book rather than assuming it — that puts it in the confirmed scope instead of in someone’s expectations. And for a genuinely loaded kitchen, the deep clean publishes its own boundary: laundry, organization, heavy pet hair, grease, patios, garages and full wall washing “require extras or review.” In the booking flow’s add-on menu that shows up as “Heavy grease or buildup,” from $75, published as a starting price whose final scope is confirmed.
