TL;DR
An air fryer that smokes almost always has grease baked onto the heating element above the basket, not in the basket itself. Unplug it, let it cool, turn the unit upside down, and soften that grease with a warm soapy cloth and a soft brush. Never scrub the element hard and never soak the housing.
The Smoke Comes From Above
An air fryer is a small convection oven with a fan. The fan drives hot air past the food, and it also flings a fine mist of fat upward onto the element and the fan guard. That fat bakes into a hard brown varnish exactly where the heat is highest.
So the basket can look spotless while the machine smokes on every cook. People wash the basket again, the smoke continues, and the actual source is a few inches above it.
Once you know where to look, this is a fifteen minute job every month or two. The pattern of grease landing where you cannot see it repeats across the guide to cleaning small kitchen appliances safely.
How Do You Clean an Air Fryer Heating Element?
Unplug the fryer, let it cool completely, remove the basket, and turn the whole unit upside down or lay it on its back so the element faces you. Wipe with a cloth dampened in warm soapy water, let it dwell a minute on stubborn spots, then work gently with a soft brush. Wipe with clean water and dry.
Go gently. The element is a coiled tube and it bends. A bent element sits closer to the food and burns it, and the coating on the tube scratches easily.
For heavy varnish, dampen a cloth with warm soapy water and drape it over the element for ten minutes before wiping. Dwell time replaces force.
Do Not Do These Things to the Element
Do not use steel wool, scouring powder, or a metal scraper. Do not use commercial oven cleaner unless the manual specifically permits it, since caustic cleaner damages the element coating and creeps into the fan housing. Source: appliance manufacturer use and care manuals
Do not run water over the element or into the housing, and never immerse the body. The fan motor and the controls sit directly behind that cavity.
Do not spray anything at the unit. Dampen the cloth away from the appliance and wipe.
The Basket, Crisper Plate, and Drawer
Wash the basket, the crisper plate, and the drawer in hot soapy water after every use, or in the dishwasher if the manual approves it. Nonstick coatings take no abrasive pads, no scouring powder, and no metal utensils, and dishwasher detergent shortens coating life on some models.
For baked-on food, soak the basket in hot soapy water for fifteen to thirty minutes and use a soft brush. A paste of baking soda works on stubborn spots and is safe on most nonstick, though a test in a corner is sensible.
The drawer beneath a basket-style unit collects rendered fat that can pool. Empty it after fatty foods rather than letting it accumulate, since a pool of hot fat is what produces the heaviest smoke.
Cleaning the Fan Guard and Cavity
The fan guard is the perforated cover behind or above the element. Wipe it with the same soapy cloth and clear the perforations with a soft brush. Do not remove the guard unless the manual describes how.
Wipe the interior walls of the cavity with a warm soapy cloth. These are usually a thin coated finish, so use a soft cloth rather than a pad, and dry them afterward.
Check the vent slots on the outside of the housing too. Grease and dust build there and restrict airflow, which makes the unit run hotter than it should.
How Often Should an Air Fryer Be Cleaned?
Wash the basket, plate, and drawer after every use. Wipe the element, fan guard, and cavity every one to two months with regular use, or immediately if the unit smokes on a normal cook. Cooking bacon, wings, or anything fatty moves that interval much closer.
Preheating an empty fryer for a few minutes will not burn off baked varnish. It just makes the kitchen smoky. Clean it properly instead.

FAQ
Why does my air fryer smoke even when the basket is clean?
Grease baked onto the heating element and fan guard above the basket is the usual cause, and it is invisible from a normal viewing angle. Unplug and cool the unit, turn it over, and wipe the element with a warm soapy cloth and a soft brush.
How do you clean an air fryer heating element?
Unplug the unit and let it cool, then invert it or lay it on its back so the element faces you. Wipe with a cloth dampened in warm soapy water, letting it dwell on stubborn spots, and work gently with a soft brush. Rinse-wipe and dry.
Can you use oven cleaner in an air fryer?
Usually no. Most manuals prohibit commercial oven cleaner because the caustic formula damages the element coating and the interior finish and can creep into the fan housing. Warm soapy water with dwell time, or a baking soda paste on the basket, is the safe approach.
Is the air fryer basket dishwasher safe?
Many baskets and crisper plates are dishwasher safe, but dishwasher detergent shortens the life of some nonstick coatings. Check the manual. Hand washing in hot soapy water with a soft sponge, after a soak if needed, keeps the coating in better shape over time.
Can I put water in the bottom of an air fryer to stop smoking?
Some manufacturers suggest a small amount of water in the drawer under a basket when cooking very fatty foods, and others do not. Follow your manual. It is a way to keep rendered fat from smoking, not a substitute for cleaning the element.
How often should I clean the inside of an air fryer?
Wash the basket, plate, and drawer after every use, and wipe the element, fan guard, and cavity every one to two months. Move to the shorter interval if you regularly cook bacon, wings, or other fatty foods, or if the unit starts smoking.
Can I scrub the air fryer element to speed things up?
No. The element is a coiled tube that bends under pressure, and its coating scratches. A bent element cooks unevenly and sits closer to the food. Use a damp soapy cloth draped over it for ten minutes to soften the varnish instead of scrubbing.
