Quick answer: unplug the air fryer, let it cool completely, remove the basket and pan, brush away loose debris with a soft to medium bristle brush, then wipe the accessible heating element and surrounding interior with a soft, damp sponge or cloth. Do not spray water or cleaner into the appliance, do not use steel wool or a hard wire brush, and do not reassemble or plug it in until everything is dry. If your model has quartz tubes, exposed wiring, or a heating assembly that the manual says not to touch, follow that model-specific instruction instead.
This guide is written for common household air fryers, especially basket-style models with an upper heating element. Designs vary significantly, so the user manual for your exact model takes priority. The recommendations below were checked against current manufacturer guidance from Philips, Ninja, and Breville on September 13, 2026.
| Task | Recommended approach | Avoid |
|---|---|---|
| Loose crumbs and baked-on bits | Soft or medium bristle brush | Wire brush, metal scraper, knife |
| Greasy film on an accessible metal element | Soft sponge or cloth dampened with warm water | Spraying liquid directly into the appliance |
| Removable basket and pan | Warm water and dish soap, if allowed by the manual | Assuming every coated part tolerates abrasive pads |
| Quartz heating tubes | Use only the method specified for that model | Treating them like a metal coil without checking the manual |
| Drying | Air-dry thoroughly before reconnecting power | Plugging in while moisture remains |
Philips specifically recommends a soft sponge with hot water for the interior and heating element and says stuck food can be removed with a soft to medium bristle brush. Its support page also warns against steel wire and hard bristle brushes because they can damage the heater coating. See the Philips Airfryer cleaning instructions. Ninja's AF100 owner guide likewise says to unplug before cleaning and use a cleaning brush on the heating element to remove food residue; see the Ninja AF100 Series Owner's Guide.
Turn the appliance off, unplug it from the wall, and wait until the heating element and interior are fully cool. Remove the basket, pan, crisper plate, and other removable accessories so you can see the upper interior clearly. Never clean the element while it is warm.
Clean removable parts separately according to the manual. Many baskets and pans can be washed with warm water and dish soap, and some are dishwasher-safe, but that does not mean the main appliance or heater can be immersed.
For a basket-style air fryer, first look up the cleaning section in the manual. Philips instructs owners of many of its models to place a soft cloth down and carefully turn the appliance upside down to reach the heating element. That is a model-specific access method, not a universal rule. If your manual does not say the unit may be inverted, leave it upright and reach the element from the basket opening instead.
Keep the power cord and plug dry. Do not place the appliance in a sink, and do not pour water into the cavity.
Look for crumbs, breading, grease flecks, or food splatter around the coil and nearby metal surfaces. Start with the least aggressive method: use a soft or medium bristle brush to loosen dry particles. Work gently around supports, bends, and the area behind the element without forcing or bending the heater.
This matters because residue can contribute to smoke during later cooking. Philips notes that greasy residue from previous use can produce white smoke and advises cleaning the pan, basket, and heating element thoroughly; see its official white-smoke troubleshooting guidance.
Dampen a soft sponge or microfiber cloth with warm water, then wring it out well. Wipe the accessible heater surface and nearby interior where the manual allows. The cloth should be damp, not dripping. Do not spray water, degreaser, or oven cleaner directly toward the heating element, fan, vents, controls, or electrical connections.
If grease does not release with gentle wiping, stop before escalating to a harsh chemical or abrasive pad. Check the exact manual. Heater materials differ. For example, Breville's Joule Oven Air Fryer Pro manual says its quartz heating elements should be rubbed gently with a soft, damp sponge or cloth and specifically says not to use cleanser on those elements. See the Breville Joule Oven Air Fryer Pro instruction book.
Return the appliance to its normal upright position if you moved it. Wipe away visible moisture, then let the interior air-dry completely. Reinstall only clean, dry removable parts. Do not reconnect power while moisture remains inside.
Some manufacturers include a model-specific final step. Philips, for example, instructs owners of many Airfryer models to run the appliance for a few minutes without food after cleaning so loosened residue falls into the pan. Do that only if your own manual tells you to. If the manual does not specify an empty run, simply allow the unit to dry and use it normally at the next cooking session.
Be especially cautious with toaster-oven-style air fryers. Some use quartz heating tubes rather than the coated metal coil commonly seen in basket models. Breville documentation varies by model: one manual permits gentle wiping of quartz elements, while another cleaning guide tells users to avoid touching them. That difference is exactly why the model number matters.
There is no single interval that fits every air fryer. A useful practical rule is to inspect the upper interior after greasy, breaded, or splatter-heavy foods and clean visible residue once the appliance is cool. Some manufacturer manuals call for cleaning the appliance after every use. Ninja's AF100 guide says the unit should be cleaned thoroughly after every use, while Philips also links grease residue with white smoke and recommends thorough cleaning after use.
If you mainly cook dry foods and the element stays visibly clean, a gentle inspection may be all that is needed. Do not repeatedly scrub a clean element just to satisfy a calendar schedule.
Stop using the air fryer and contact the manufacturer or an authorized service provider if you see a cracked or distorted heating element, exposed wiring, loose heater supports, melted plastic, repeated electrical tripping, persistent arcing, or smoke that continues after visible food and grease residue have been removed. Cleaning cannot repair an electrical or structural fault.
A strong odor during the first few uses can also have model-specific explanations, so check the manual before assuming the heater is dirty. Conversely, if an older unit suddenly develops a burning smell, inspect for trapped food only after unplugging and cooling it.
For most basket-style units, the safest default is simple: dry brushing first, then a well-wrung soft sponge or cloth with warm water. The moment your air fryer uses a different heater design or its manual gives different instructions, follow the manufacturer-specific method instead.
