The non-stick coating, and when a basket is finished

Questions this answers

• Why is my air fryer basket peeling?
• Is it safe to use an air fryer with a scratched coating?
• How do I stop the non-stick wearing out?
• When should I replace the basket?
• Can I use metal utensils in an air fryer?

What actually wears it

Three things, and the manuals in this catalogue are unusually united about all three. Metal utensils dragged across the surface. Abrasive cleaning — scouring pads, steel wool, abrasive powders and creams. And heat with nothing in the pan, which is a smaller risk in an air fryer than in a frying pan but is not nothing.

Cosori's manual states that the basket and crisper plates carry a non-stick coating and that metal utensils and abrasive cleaning materials are to be avoided. Instant Brands states that metal cleaning utensils must not be used on the non-stick cooking tray. Tower states that scouring pads, steel wool and any strong solvent or abrasive cleaning agent must not be used on the appliance or its accessories. Ninja lists the dishwasher-safe parts and then recommends hand-washing them anyway, specifically to extend their life.

That last one is worth sitting with. A manufacturer telling you not to use a feature it has certified is a manufacturer telling you the part is a consumable.

The care, which is four sentences long

Keep metal off it. Silicone or wooden tongs and spatulas cost a few pounds and are the whole of the intervention.

Soak rather than scrub. Hot soapy water and time does what force does, without the force. Cosori publishes its own method for baked-on grease — a paste of baking soda and water, spread on, left for fifteen minutes, then rinsed and washed normally — which is a manufacturer explicitly offering an alternative to abrasion.

Hand-wash where you can, even where the dishwasher is permitted. Dishwasher detergent is aggressive and the cycle is long.

Do not stack anything inside the basket in a cupboard. A crisper plate rattling against a basket in a drawer does the same damage a fork does, more slowly.

What the coating is made of

No manual read for this catalogue names the material. Philips, Tefal, Tower, Cookworks and Instant each describe the coated parts as having a non-stick coating, Ninja's parts list says non-stick drawers, and that is where every one of them stops. None says PTFE, none says ceramic, none says PFAS-free, and none gives a temperature the coating is rated to.

So for the machines on this site the material is not verified, and AirfryerHQ will not infer it. Non-stick describes what a surface does and not what it is made of: a ceramic-coated basket and a PTFE-coated one are sold under the same two words. If the material matters to you, the manufacturer's own specification or its customer service is where it is stated, when it is stated at all.

What the manuals do say is how to treat it, and on that they agree: no metal utensils and nothing abrasive. Which parts are coated differs from machine to machine. On one it is the drawer and the plate, on another the inside of the chamber as well, and on an oven-style machine it can be the drip tray alone, so each model page here gives its own manual's wording.

When the coating has already gone

First, what AirfryerHQ will not tell you: whether flaking coating is a health risk. There is a great deal of confident content in both directions and we hold no toxicological evidence, no food-contact standard and no independent authority's statement on the question. Asserting that it is fine would be as unsupported as asserting that it is dangerous, and we are not going to do either.

What can be said is what the manufacturers say, and what follows from the appliance working properly. A coating that is peeling is a coating that is coming off, which means pieces of it are ending up somewhere, and a basket whose surface is breaking down sticks more, cleans worse and needs more scrubbing — which accelerates the same failure. Every manual in this catalogue treats the coated parts as things to be protected, which is a clear signal about what a damaged one means.

One manufacturer does address it in print. The troubleshooting tables in Philips's manuals for the basket and steam models here say that small spots can appear inside the pan where the coating has been touched or scratched, that small pieces can chip off if the basket or plate is lowered in at an angle, and that this is not harmful because the materials used are food-safe. That is Philips speaking about Philips's own pans. It is not a statement about anybody else's coating, and it is not a toxicological finding.

The practical position: a scratch is not a crisis and a surface that has begun to flake is the end of that part's working life. Replace the part if you can get one, and if you cannot, the appliance has reached the end rather than the part.

If you want a definitive safety answer, the manufacturer of your specific appliance is the body that can give one about their own coating, and asking them is a reasonable thing to do.

Why this decides how long the appliance lasts

An air fryer has very few parts that wear. The motor and the element are not handled, not washed and not scraped; the basket and crisper plate are handled, washed and scraped every single time it is used. So the coating is the thing that fails, and whether a replacement can be bought is what determines whether a five-year-old machine is repairable or refuse.

That is worth thinking about before you buy rather than after. Spare-part availability is not something AirfryerHQ holds for any manufacturer, and it is thirty seconds on a manufacturer's spare-parts page.

What AirfryerHQ has not established

How long a coating lasts, with or without metal utensils. No durability data of any kind is held, and the advice above is what manufacturers instruct rather than what has been measured.

Anything at all about the health implications of ingesting coating fragments. No source we hold addresses it and this page makes no claim in either direction.

What any coating is made of. Manufacturers in this catalogue describe their parts as non-stick without naming a chemistry, so this page does not name one either.

The method, part by part

Basket — Ordinary residue after cookingThe basket and crisper plate, after every use — Warm soapy water or the dishwasher on most models, and never anything abrasive — the coating is the part that does not grow back.

Basket — Burnt-on residueBurnt-on grease on a basket or crisper plate — One manufacturer publishes an actual method — a baking-soda paste left for fifteen minutes — and it is the only sourced one in this catalogue.

Basket — Ordinary residue after cookingWhich parts are dishwasher safe — Most baskets and plates on the models we hold are. One accessory is explicitly not, and one whole machine publishes no permission at all.

Basket — Stuck foodFood stuck to the basket or plate — Soak it. Everything else risks the coating, and the coating is why it stuck.

Crisper plate — Looking after the coatingLooking after the nonstick coating — The coating is the shortest-lived part of an air fryer and almost everything that shortens it is avoidable.
