How to clean an air fryer: after every use, unplug it and let it cool, then wash the basket and crisper plate in hot soapy water (or the dishwasher if the manufacturer allows). Wipe the interior with a damp cloth, clean the heating element with a soft brush monthly, and deep-clean baked-on grease with a baking-soda paste. The whole routine takes 5 minutes daily and prevents the sticky buildup, smoke, and odors that plague neglected air fryers.
This guide is research-based: we compiled manufacturer care instructions from Ninja, COSORI, Philips, and Breville, plus the cleaning methods most recommended in verified owner reviews. Below you’ll find the daily 5-minute routine, the monthly deep-clean protocol, heating-element care, odor and smoke troubleshooting, what never to do, and an FAQ on the questions owners ask most.
The Daily 5-Minute Routine (After Every Use)
Step 1: Unplug and cool down
Always unplug first — never clean a plugged-in appliance. Let the fryer cool for 20–30 minutes until warm to the touch, not hot. Cleaning while warm (not hot) is actually ideal: grease hasn’t fully hardened, so it wipes away easily. Don’t rush it under cold water — thermal shock can warp baskets and damage nonstick coatings.
Step 2: Wash the basket and crisper plate
Remove the basket and crisper plate/tray. Wash in hot water with dish soap and a non-abrasive sponge — the soft side, never the scouring side. Most manufacturers (Ninja, COSORI, Philips) certify their baskets as dishwasher-safe, and the dishwasher is fine for daily cleaning. But hand-washing extends nonstick life significantly: dishwasher detergents are abrasive and high heat degrades coatings over time. If you use the dishwasher, skip the heated-dry cycle.
Step 3: Wipe the interior
Dampen a cloth or paper towel with hot soapy water, wring it well, and wipe the interior walls and the inside of the lid/door. Pay attention to the crevices around the basket rails where grease spatters collect. For oven-style models, remove and wash the racks and drip pan separately.
Step 4: Dry everything completely
Towel-dry the basket and plate, then let them air-dry fully before reassembling. Trapped moisture causes musty odors and can corrode uncoated metal parts over time. Never reassemble a damp air fryer and close it up — that’s how mildew starts.
Step 5: Wipe the exterior
A quick wipe of the housing with a damp cloth keeps the exterior looking new and prevents the greasy film that builds up on frequently touched surfaces. For stainless-steel models, wipe with the grain using a microfiber cloth.
The Monthly Deep Clean: Removing Baked-On Grease
Even with daily cleaning, polymerized grease builds up over weeks — the sticky, amber-colored film that soap alone won’t touch. Monthly deep cleaning resets it:
The baking-soda paste method
Mix 3 tablespoons of baking soda with 1 tablespoon of water into a thick paste. Apply to the greasy areas of the basket, tray, and interior walls (avoid the heating element — more on that below). Let it sit 15–20 minutes, then scrub gently with a soft brush or old toothbrush. The mild abrasion of baking soda cuts through polymerized grease without scratching nonstick. Rinse and wash normally afterward.
The steam-clean trick
For oven-style air fryers and stubborn interiors: place an oven-safe bowl with 1 cup of water and 2 tablespoons of lemon juice inside, run at 300°F for 10 minutes, then let it cool and wipe. The steam loosens baked-on residue dramatically — it’s the same principle as oven steam-cleaning cycles.
Degreasing the drip pan and racks
Soak removable racks, drip pans, and rotisserie accessories in hot water with dish soap and 1/2 cup of baking soda for 30 minutes. For extreme buildup, a paste of baking soda and hydrogen peroxide (3%) left for 20 minutes dissolves what soaking can’t. Rinse thoroughly.
Cleaning the Heating Element (The Part Everyone Forgets)
The heating element — the coil at the top of the chamber — collects grease spatter that burns on with every use. Neglected, it becomes the #1 source of smoke and burning smells.
How to clean it safely
1. Unplug and cool completely (at least an hour — the element retains heat). 2. Turn the unit upside down or tilt it so the element faces you (check your manual — some manufacturers advise against inversion; if so, work carefully from below). 3. Use a soft-bristle brush or old toothbrush to gently dislodge loose debris — never use metal tools or abrasive pads on the element. 4. Dampen a cloth with hot water (wrung nearly dry) and wipe the element gently. For stubborn spots, a paste of baking soda applied sparingly, left 10 minutes, then wiped off. 5. Let it dry completely before plugging in — at least 2 hours, or run the empty fryer at 350°F for 5 minutes to evaporate residual moisture.
How often?
Inspect monthly; clean when you see visible buildup or notice smoke during cooking. Heavy users (daily frying of fatty foods) should check every 2–3 weeks. A clean element is the difference between a fresh-smelling fryer and one that smokes out the kitchen.
Removing Odors: Fish, Garlic, and Mystery Smells
Air fryers absorb odors because hot grease vapor deposits on every interior surface. These methods work:
The lemon-steam deodorizer
Cut a lemon in half, place it in the basket with 1 cup of water, and run at 350°F for 10 minutes. The citric-acid steam neutralizes odor compounds. Wipe down afterward. This handles most everyday smells.
The baking-soda overnight treatment
For stubborn odors (fish, burnt popcorn): place an open bowl of baking soda inside the cooled fryer, close it, and leave overnight. Baking soda absorbs volatile odor molecules. Repeat for 2–3 nights for severe cases.
The vinegar wipe
Wipe interior surfaces with a cloth dampened in equal parts white vinegar and water. Vinegar’s acetic acid dissolves grease films that trap odors. The vinegar smell dissipates as it dries — follow with a plain-water wipe if you’re sensitive to it.
Preventing odors in the first place
The best cure is prevention: clean after every use (don’t let grease sit), leave the basket slightly open after drying (airflow prevents mustiness), and cook strongly aromatic foods (fish, garlic-heavy dishes) with the kitchen ventilated. Silicone basket liners also reduce odor absorption into the coating.
Why Is My Air Fryer Smoking? Causes & Fixes
White smoke during cooking has three common causes, in order of likelihood:
1. Grease buildup on the element or interior walls (most common) — old grease reheats past its smoke point. Fix: deep-clean the element and interior as described above.
2. Excess fat in the food — fatty foods (bacon, duck, 80/20 burgers) render more grease than the drip system handles; droplets hit the hot element and smoke. Fix: add 2 tablespoons of water to the drip pan/drawer below the basket — it cools the grease below its smoke point (the PowerXL’s design principle).
3. Wrong oil — low-smoke-point oils (extra-virgin olive oil, unrefined) smoke at air-fryer temperatures. Fix: use high-smoke-point oils (avocado, refined peanut, light olive oil) or skip oil entirely.
Black smoke or electrical smells are different — unplug immediately and inspect for melted plastic or damaged wiring. That’s a safety issue, not a cleaning issue.
What NEVER to Do: 7 Air Fryer Cleaning Mistakes
1. Never submerge the main unit — the base contains electronics and the fan motor. Water intrusion causes shorts and corrosion. Only removable parts get wet.
2. Never use metal utensils or steel wool — they scratch nonstick coatings, and scratched coating flakes into food and loses its release. Silicone, wood, and soft plastic only.
3. Never use aerosol cooking spray — the propellants and additives bake into a gummy polymer layer that’s nearly impossible to remove and ruins nonstick over time. Use a pump mister with pure oil instead.
4. Never use oven cleaner or bleach — caustic oven cleaners destroy nonstick coatings and leave toxic residues; bleach corrodes metal parts. Baking soda, dish soap, and vinegar handle everything safely.
5. Never clean while plugged in — obvious but worth stating: water + electricity + heating elements is a genuine hazard.
6. Never put a hot basket under cold water — thermal shock warps the basket and can crack nonstick coatings. Let it cool to warm first.
7. Never ignore the exterior vents — blocked air-intake and exhaust vents cause overheating. Wipe them monthly with a dry cloth to remove dust and grease film.
Extending Nonstick Life: Make Your Basket Last Years
The basket’s nonstick coating is the consumable part of an air fryer — but “consumable” can mean 1 year or 5 years depending on care. Maximize it: hand-wash instead of dishwashing when convenient; never use metal utensils; avoid aerosol sprays; don’t overheat the empty basket (preheat with food or for the minimum time); store with a soft cloth inside to prevent scratching; and replace the basket — not the whole fryer — when coating finally wears (replacement baskets are available for Ninja, COSORI, and Philips models). A $25 replacement basket beats a $150 new fryer.
The easiest way to protect your coating daily: perforated parchment liners or reusable silicone liners. They catch drips, prevent baked-on messes, and lift out for quick cleaning — many owners say liners doubled their basket’s nonstick life.

Frequently Asked Questions
Can you put an air fryer basket in the dishwasher?
Most manufacturers certify their baskets as top-rack dishwasher safe (Ninja, COSORI, Philips all do). However, hand-washing extends the nonstick coating’s life significantly — dishwasher detergents are abrasive and high-heat drying degrades coatings. Dishwasher for convenience, hand-wash for longevity.
How often should you clean an air fryer?
Wipe down and wash the basket after every use (5 minutes), deep-clean baked-on grease monthly, and inspect/clean the heating element monthly. Heavy users should deep-clean every 2–3 weeks. Neglecting cleaning causes smoke, odors, and off-flavors — and can be a fire hazard with extreme grease buildup.
Can I use oven cleaner in my air fryer?
No — caustic oven cleaners destroy nonstick coatings and can leave toxic residues in the small chamber. Use baking soda paste, dish soap, and vinegar instead. They’re safer, cheaper, and effective on everything short of industrial carbonization.
Why does my air fryer smell like plastic?
New air fryers often smell plasticky for the first 2–3 uses — manufacturing residues burning off the element and interior. Run it empty at 400°F for 15–20 minutes (ventilated) before first cooking; the smell should vanish. If a used fryer suddenly smells like plastic, unplug it and inspect for melted components — that’s a safety issue.
How do you get baked-on grease out of an air fryer?
Baking soda paste (3 tbsp soda + 1 tbsp water), applied for 15–20 minutes then scrubbed with a soft brush, dissolves most polymerized grease. For extreme cases, the steam-clean method (water + lemon at 300°F for 10 minutes) loosens what paste can’t. Avoid abrasive pads that damage nonstick.
Is it safe to use parchment paper or foil in an air fryer?
Yes, with rules: never preheat with loose paper/foil (the fan blows it into the element — a fire hazard); always weigh it down with food; don’t cover the entire basket floor (blocks the airflow that makes air frying work); and use perforated parchment liners designed for air fryers for best results. Silicone liners are the reusable alternative.
When should you replace an air fryer?
Replace when: the nonstick coating is extensively flaked or scratched (and replacement baskets aren’t available), the fan makes grinding noises, the element heats unevenly, or you see any electrical issues (sparking, melting smells). With good care, quality air fryers last 3–5 years; the basket coating is usually the first thing to go.
Can I use silicone liners and accessories?
Yes — food-grade silicone liners, muffin cups, and cake pans rated for 450°F+ are safe in air fryers and dramatically reduce cleanup. They also protect the nonstick coating from utensil scratches. Avoid cheap unbranded silicone (possible fillers); stick to reputable brands. Metal accessories (racks, skewers) are fine too, as long as they fit without touching the heating element.
