Quick answer
White smoke from an air fryer is usually old grease burning, not a broken machine. Unplug it, let it cool and scrub the basket, drawer and heating element; a narrow brush set reaches the corners a sponge misses, so the film does not build back up. Black smoke, a burning-plastic smell or sparks mean stop using it.
Free fix vs. permanent fix
Soak, scrub and wipe the element
- Unplug it and let it cool for 30 minutes
- Soak the basket and drawer in hot soapy water for 10 to 15 minutes
- Wipe the heating element with a damp, soapy cloth
- Use 1 to 2 teaspoons of refined oil and empty the drawer halfway
How long it lasts: Clears most smoke right away. It returns if a film is left in the corners and cooks on again.
A long-handle brush and soft scraper set
The film that smokes hides under the basket and in the drawer corners, where a sponge cannot reach. A narrow brush and scraper clear it in minutes, so you keep doing it and the grease never gets time to bake on.
What to get: Air fryer cleaning brush set (long-handle brush plus soft scraper)
How long it lasts: Reusable for years, and it keeps the film from building up as long as you use it after greasy cooks.

Why it happens
Old grease in the drawer
A thin film of baked-on fat under the basket heats up on every cook and starts to smoke. It is the most common cause, and it worsens each time the grease cooks on again.
Fatty food
Bacon, sausage, burgers and skin-on chicken release a lot of fat. In a small, hot chamber it drips onto a very hot drawer and smokes within minutes.
Too much oil, or the wrong kind
Heavy oil pools and burns. Butter and unrefined oils smoke at lower temperatures than refined avocado or canola oil.
Crumbs on the heating element
Splatter and crumbs stuck on or near the element burn each time it heats up. You often smell this before you see smoke.
A new unit or a worn coating
A brand-new air fryer can give off a light smell or a little smoke in its first few uses. A flaking or peeling nonstick coating can also smoke.

Do these in order, starting with the simplest.
-
Unplug it and let it cool
Never clean it hot or plugged in. Wait at least 30 minutes, then pull out the basket and drawer.
-
Soak the basket and drawer
Tool used: Hot soapy waterSoak both in hot soapy water for 10 to 15 minutes so the baked-on film softens. Dry fully before putting them back.
-
Scrub the corners and underside
Tool used: Long-handle brush and soft scraperA sponge handles the flat parts. A narrow brush and soft scraper get the corners and the underside of the basket, where the film that smokes hides. An old toothbrush works if you have no brush.

-
Wipe the heating element
Tool used: Damp microfiber clothWith the unit cool and unplugged, check your manual for how to reach the element. Many models turn on their side. Wipe it with a damp, soapy cloth, then a clean damp one. Never spray liquid into the housing.
-
Line the basket for greasy food
Tool used: Perforated parchment linersPat meat dry, do not overfill, and empty the drawer halfway through a long cook. A perforated liner catches fat if you weigh it down with food. Some manuals say a splash of water in the drawer cuts smoke from fatty food, so check yours.

Use less oil, and the right kind
Tool used: Oil misterToss food with 1 to 2 teaspoons of refined avocado, peanut or canola oil. A mister spreads a thin coat. Save butter and extra virgin olive oil for after cooking.

When free fixes aren't enough
If you have scrubbed everything and it still smokes, or the smoke returns after a few greasy cooks, the film is hiding where a sponge does not go, or you cook fatty food often. A brush set clears those spots in minutes, and liners keep fat off the drawer. If the nonstick coating is flaking, no cleaning helps, so ask the maker for a replacement basket. Black smoke or a burning-plastic smell is not grease: unplug it and stop.

How to tell grease smoke from electrical smoke
Grease smoke: white or gray, smells like hot cooking fat, and fades once you unplug the unit and let it cool. This is the normal, fixable kind.
Electrical smoke: black smoke, a sharp burning-plastic or fishy smell, sparks, crackling, or a melted housing or cord. Unplug the unit at the wall if you can do it safely, and do not use it again. Contact the maker. If you see flames, call 911 and never throw water on an appliance fire.
Foods that smoke most, and what to do
- Bacon and sausage: lower the heat a little and empty the drawer halfway.
- Burgers: use a rack if your model has one, so fat drops away.
- Skin-on chicken: trim loose fat and pat the skin dry.
- Sugary marinades: wipe off the excess and glaze in the last few minutes.
What to skip
Aerosol cooking spray and steel wool
Aerosol sprays can leave a sticky film on nonstick coatings, and several air fryer makers say to avoid them. Steel wool and scouring pads scratch the coating, and a scratched coating is what makes smoke and smells come back. Use an oil mister with plain oil and wash with a soft sponge.
