To clean an air fryer: let it cool completely, pull the basket and tray, and wash both in warm water with dish soap, then wipe the interior and the heating element with a damp cloth. Do that after every use and a deep clean is rarely needed. Skip a few sessions and grease bakes onto the coil, and that's when the smoke alarm starts auditioning.
Most air fryer smell and smoke complaints trace back to the same thing: oil residue left to harden instead of wiped away while it was still soft. Below is the daily version, the deep-clean version for when you've fallen behind, what's actually causing the smell, and the handful of things that will scratch a nonstick basket faster than baked-on grease ever could.
The short version
Wipe it down after every use: basket and tray in warm soapy water, interior and heating element with a damp cloth, everything dry before it goes back together. For baked-on grease, soak the basket in hot water and dish soap for fifteen to twenty minutes, then a baking soda paste on anything that's still stuck. Deep clean the heating element every one to two weeks depending on how often you cook. Never touch a nonstick basket with steel wool, metal utensils, or an abrasive scouring pad — a single scratch is enough to start flaking the coating into your food. Once everything's washed and dried, a Gentle Sen wipe-down leaves the basket smelling like nothing at all, which is exactly what an air fryer basket should smell like.

How Often to Clean It
The quick wipe-down happens every time you use it, full stop — that's not a deep clean, it's just emptying crumbs and rinsing the basket before grease has a chance to set. The actual deep clean, the one that gets into the heating element and any grease that's already hardened, is a different schedule.
Cook fatty foods most days — wings, bacon, anything breaded — and a deep clean once a week keeps up with it. Cook lighter, more occasional meals and every two weeks is usually fine. The more reliable signal than any calendar is the air fryer itself: visible smoke on preheat, a burnt smell that wasn't there last week, or food picking up an off flavor all mean it's overdue regardless of what day it is.
The After-Every-Use Wipe-Down
This takes about three minutes and it's the single habit that keeps you out of the deep-clean section entirely.
-
1
Unplug it and let it cool completely. The basket, the tray, and the interior walls all hold heat longer than they look like they should.
-
2
Pull the basket and tray and wash them in warm water with a few drops of dish soap, using a soft sponge, not the scrubbing side.
-
3
Wipe the interior and the exposed heating element with a damp microfiber cloth. A toothbrush or a wooden skewer gets into the gap between the element and the housing, where crumbs like to hide.
-
4
Dry everything fully before reassembling. A damp basket sealed back into a warm unit is exactly the environment that grows a smell overnight.
Deep Cleaning Baked-On Grease
If it's been a few weeks, or the basket already has that faint amber tint that says "grease has opinions now," a soak does the work a wipe-down can't.
-
1
Fill the sink or basket with hot water and dish soap, and soak for fifteen to twenty minutes. Stubborn grease gets an hour — walk away, don't scrub harder.
-
2
Make a paste from baking soda and a little water, and spread it over anything still stuck. Let it sit ten minutes before working it with a soft sponge.
-
3
For the heating element itself, dip a soft-bristled brush in warm soapy water and work along the coil, then wipe with a damp cloth to lift the loosened residue.
-
4
Rinse everything thoroughly and let it air-dry completely before the basket goes back into the unit.
A diluted vinegar-and-warm-soapy-water mix is worth a second pass on anything the baking soda didn't fully lift — the mild acidity helps break the grease film loose without touching the nonstick coating.
Why an Air Fryer Starts Smoking or Smelling
Every time oil splatters onto the heating element or the basket walls and doesn't get wiped off, it gets cooked again on the next run. Heat repeated on the same thin film of fat drives off moisture and breaks the oil down — a process called thermal cracking — and part of what's left behind is a carbon residue that bonds to the metal instead of rinsing away with plain water. Do that enough times and you've built a layer that smokes at temperatures the oil never used to smoke at on its own.
That's the same mechanism behind why a well-used cast iron pan builds up a black coating researchers call "baked lard soiling" — a layer that ordinary detergent alone struggles to shift once it's fully hardened, which is exactly why the soak-first, then-scrub approach in the deep-clean section above matters more than scrubbing harder from the start.
The smell that comes with it is a mix of that scorched-fat odor and whatever seasoning or marinade was on the last few meals, slowly baking into the same film. It's not dangerous in the amounts a home kitchen produces, but it's also not something a candle is going to fix — the residue has to physically come off.
What Never to Use on an Air Fryer Basket
Steel wool, metal scouring pads, and metal utensils top the list. Most air fryer baskets have a nonstick coating, and even one scratch gives grease a rougher surface to grip onto — which means it builds up faster next time, not slower. Independent testing on scratched nonstick coatings has found the damage can shed thousands of microscopic coating particles into food, which is reason enough to retire a visibly scratched basket rather than keep cooking in it.
Bleach doesn't belong here either. It's not formulated to break down grease, it can pit some basket coatings, and boiling residue off a food-contact surface with it is a good way to end up tasting chlorine in your next batch of fries.
Check the manual before the dishwasher, not after. Some baskets and trays are dishwasher-safe and some aren't — high heat and detergent can dull a nonstick coating faster than hand-washing does, even on models the manufacturer lists as safe.
Where Gentle Sen Actually Fits Into This Routine
We'll say the honest version up front: Gentle Sen tablets are not a degreaser. Dish soap and a baking soda paste are what break down baked-on oil, and nothing above changes that. Where our tablets earn a spot is after the grease is gone.
After the basket and tray are washed and dried, dissolve one Gentle Sen tablet in 20 fl. oz. of lukewarm water and wipe down the basket, tray, and exterior housing. It's fragrance-free, so there's no lingering scent to compete with whatever you're cooking next, and it's food-contact safe with no rinse required, so it's a fast last step rather than another washing cycle.
It's also worth a swipe on the exterior handle and control panel, which get touched with greasy fingers as often as the basket does but rarely get cleaned at all. See our full list of ways to use Gentle Sen tablets for the ratios we use elsewhere in the kitchen.
If a product claims it can dissolve baked-on grease in one wipe, read the ingredient list — that's usually a degreaser or a solvent doing the work, not an HOCl solution. We'd rather tell you which job our tablets are actually good at.
A Clean Air Fryer Is a Quiet, Odor-Free Air Fryer
Wipe it down after every use, soak and paste your way through anything that's already hardened, and keep steel wool nowhere near the basket. That's most of the job done before it ever becomes a smoke-alarm problem.
Once it's washed and dry, a Gentle Sen wipe-down handles the smell and the handle grime — the two things soap alone tends to leave behind.

How often should you clean an air fryer?
Wipe the basket and tray after every use. A deeper clean of the heating element and any baked-on residue should happen weekly if you cook fatty foods often, or every two weeks for lighter, less frequent use.
Can you put an air fryer basket in the dishwasher?
Check the manual first — some baskets and trays are dishwasher-safe and some aren't. Even on models listed as safe, hand-washing with warm soapy water is gentler on the nonstick coating over time.
How do you get baked-on grease out of an air fryer?
Soak the basket in hot water and dish soap for fifteen to twenty minutes, then work a baking soda paste into anything still stuck with a soft sponge. A diluted vinegar rinse afterward helps lift what the paste didn't fully remove.
Why does my air fryer smoke or smell burnt?
Oil splatter left on the heating element or basket walls gets cooked again on every subsequent run, breaking down into a carbon residue that bonds to the surface and smokes at lower temperatures than fresh oil does. Regular wipe-downs after each use prevent the buildup that causes it.
Can you use steel wool on an air fryer basket?
No. Steel wool and abrasive scouring pads scratch nonstick coatings, and a scratched surface both sheds coating material into food and gives future grease more texture to cling to, making buildup worse over time.
How do you clean the heating element of an air fryer?
With the unit unplugged and cool, work a soft-bristled brush dipped in warm soapy water along the coil, then wipe with a damp cloth to lift the loosened residue. Never submerge the heating element or the main unit in water.
Can you use vinegar to clean an air fryer?
Yes, diluted with warm soapy water, as a second pass on grease a baking soda paste didn't fully lift. It's mild enough not to damage nonstick coatings when used this way.
Can you use hypochlorous acid to clean an air fryer basket?
HOCl solutions like Gentle Sen tablets are food-contact safe and work well as a fragrance-free wipe-down after the basket is already washed and dried, but they aren't a degreaser — dish soap and a baking soda soak are what remove baked-on grease.
