AIR FRYER 101
How to Clean an Air Fryer: Daily Habits, Deep Cleans, and What Never to Do
The two-minute after-dinner routine, the baking soda fix for baked-on grease, and the parts of your air fryer that must never touch water.
A dirty air fryer tells on itself: white smoke on preheat, a whiff of last week's fish in tonight's fries, and a nonstick basket that suddenly sticks. None of that is the machine failing — it's old grease and stuck-on crumbs doing exactly what burnt grease does. The fix takes two minutes a day and one short deep clean a week.
Here's the full routine: the after-every-use basket wash, the baking soda paste that dissolves baked-on grease, the safe way to clean the heating element, the mistakes that permanently ruin nonstick coatings, and a steam trick that deodorizes the whole machine.
Why a dirty air fryer ruins your food
Every fatty thing you cook leaves a deposit. Make air fryer bacon and the drawer collects rendered grease; roast anything with oil and a fine film settles on every surface. Next time the machine heats to 400 degrees, that leftover grease burns — and burnt grease means white smoke, an acrid smell, and off flavors transferred straight onto fresh food.
Buildup also works the machine harder. Grease and crumbs on the heating element and around the air vents disrupt the airflow the whole appliance depends on, which means longer cook times, uneven browning, and a shorter life for the machine. A clean air fryer isn't about looks — it's the difference between an appliance that lasts two years and one that lasts ten.
After every use: the two-minute clean
Unplug the machine and let the basket cool until you can handle it — warm is fine, hot is not. Pull out the basket and drawer, wash both in warm soapy water with a non-abrasive sponge, rinse, and dry completely before sliding them back in. If grease has already cooled and clung, a 10-minute soak in hot soapy water loosens it without any scrubbing.
Most baskets and crisper plates are dishwasher-safe on the top rack — the ones in our Ninja air fryer are — but check your manual, because coatings vary by brand. Even on dishwasher-safe parts, handwashing is gentler on the nonstick and keeps it slick longer. Either way, the rule is simple: the removable parts get washed every single use, not every few uses.
The weekly deep clean: baking soda paste
Once a week — or whenever you spot stuck-on grease the sponge won't lift — mix baking soda with just enough water to form a spreadable paste. Coat the greasy spots inside the basket and drawer, let it sit for 10 to 15 minutes, then scrub with a soft-bristled brush. An old toothbrush is the perfect tool for the basket's mesh and the corners of the crisper plate.
Baking soda is mildly abrasive — enough to break down polymerized grease, gentle enough to leave the nonstick coating alone. Rinse thoroughly and dry before reassembling. While the parts dry, wipe out the interior cavity with a damp soapy cloth, then a clean damp cloth, to catch the grease film on the walls.
The heating element: careful, not fearful
The coil at the top of the cooking chamber collects grease vapor, and when that layer burns, it's the number-one source of mystery smoke. Cleaning it is safe with two non-negotiables: the machine is unplugged, and it is completely cool. Then turn the unit on its side or upside down so you can see the element, and wipe it with a damp — not dripping — cloth.
For crusty spots, a soft brush loosens debris, and a cloth dampened with soapy water followed by a clean rinse-wipe handles the grease film. Let everything air-dry fully before plugging back in. That's the whole job — two minutes, once or twice a month, and the smoke never starts.
What not to do (nonstick has no undo button)
Never use steel wool, scouring pads, or abrasive powders on the basket — one aggressive scrub session scratches the nonstick coating permanently, and food sticks to those scratches forever after. Same goes for metal utensils scraping around inside the basket during cooking. Soft sponges, soft brushes, silicone tools: that's the whole approved list.
Skip oven cleaner and other harsh degreaser sprays too — they're formulated for bare oven enamel and will attack an air fryer's coatings. And never submerge or dunk the main unit in water or run water into the cooking chamber: it houses the heating element, the fan, and the electronics. Removable parts get the sink; the main unit only ever gets a wrung-out cloth.
Deodorizing, and how often to do all this
If the machine holds onto a smell — fish and bacon are the usual suspects — steam it out. Fill a small oven-safe ramekin with equal parts water and white vinegar, or water with a couple of lemon wedges squeezed in, set it in the basket, and run the air fryer at 350 degrees for about 3 minutes. Let it cool, then wipe the interior dry. The steam loosens grease film and carries the odor out with it.
The schedule that keeps you out of trouble: basket and drawer after every use, baking soda deep clean weekly (or every couple of weeks if you rarely cook greasy foods), heating element check monthly. It's the same logic as how to clean a Keurig — small appliances don't demand much, but they demand it on a schedule, and the machine that gets two minutes a day never needs two hours on a Saturday.

Read our Ninja Air Fryer reviewFrequently asked questions
Can I put my air fryer basket in the dishwasher?
Usually yes — most baskets, drawers, and crisper plates are dishwasher-safe on the top rack, but check your manual because coatings vary by brand. Handwashing in warm soapy water is gentler on the nonstick and helps it last longer.
How do I clean baked-on grease out of an air fryer?
Make a paste of baking soda and a little water, spread it over the stuck-on grease, let it sit 10 to 15 minutes, and scrub with a soft-bristled brush or old toothbrush. Rinse and dry completely before reassembling.
How do I clean the air fryer heating element?
Unplug the machine and let it cool completely, then tip it over and wipe the element with a damp cloth, using a soft brush for crusty spots. Never spray water into the unit or submerge it — the main housing holds the electronics.
Why does my air fryer smoke when nothing is burning?
Leftover grease is burning — either pooled in the drawer or coating the heating element. Empty and wash the drawer after every use, wipe the element monthly, and add 2 tablespoons of water to the drawer when cooking fatty foods like bacon.
How often should I deep clean my air fryer?
Wash the basket and drawer after every use, do a baking soda deep clean weekly if you cook greasy foods (every two weeks otherwise), and check the heating element about once a month.
How do I get the fish smell out of my air fryer?
Run a steam cycle: place a small oven-safe dish of equal parts water and white vinegar (or water with lemon) in the basket and run the machine at 350 degrees for about 3 minutes, then wipe the interior dry. Stubborn odors also lift after an overnight sit with baking soda in the basket.
