How to clean an air fryer without wrecking the basket

Air fryers are easy to clean and easy to clean badly. The basket is the obvious part and the part everyone does; the element and fan above it are the parts that quietly accumulate grease, start to smoke, and eventually make everything taste faintly of last month's fish. Ten minutes a month prevents all of it.

There is also a real financial reason to get this right. The nonstick coating is the component with the shortest life in the machine, and how you clean it is the single biggest factor in how long it lasts. A basket scrubbed with a metal pad will be flaking within a year; the same basket treated properly will outlast the rest of the appliance.

After every use: the two-minute routine

Unplug the machine and let it cool enough to handle — not cold, just safe. Warm is actually the easiest state to clean, because grease has not yet set. Take out the basket and the crisper plate, and wash both in hot water with dish soap and a soft sponge or cloth. Pay attention to the underside of the crisper plate and the holes in it, which is where residue collects and where blocked airflow starts. Wipe the interior walls and the bottom of the cooking chamber with a damp cloth. Dry everything before it goes back in.

If food is stuck on, do not attack it. Fill the basket with hot soapy water and leave it for fifteen minutes, then it will lift with a sponge. Soaking is the whole trick, and it is gentler on the coating than any amount of scrubbing.

Once a month: the part everyone forgets

Turn the machine off at the wall, let it cool completely, and then look at the heating element and fan guard above where the basket sits. Many machines can be tipped carefully on their back to make this visible. Grease vapour rises during every cook and condenses here, and because you never see it, it builds for months. A cloth or soft brush dampened with hot soapy water — well wrung out, so nothing drips into the electrics — takes it off. Finish with a clean damp cloth and let it dry fully before plugging in.

This is the fix for two of the most common complaints about older machines: a burning smell during preheating, and food that tastes vaguely of whatever was cooked previously. Both are accumulated grease on the element, not a fault.

Four things that wreck a coating

Metal utensils and metal scourers. The most obvious and the most common. A steel wool pad will visibly score a nonstick surface on first use, and once the coating is broken it degrades from that point outward. Use silicone or wooden tongs in the basket and a soft sponge on it.

Abrasive powders and oven cleaner. Cream cleansers and caustic oven sprays are designed for bare enamel and steel, not for coated aluminium. Oven cleaner in particular can attack both the coating and the finish beneath it.

The dishwasher, when it is not cleared for it. Plenty of baskets are dishwasher-safe and say so — the manual is the authority, not the internet. Where it is not stated, hand washing is the safe assumption, because dishwasher detergents are far harsher than dish soap and long hot cycles accelerate coating wear even on parts that tolerate it.

Cooking spray in aerosol form. This one surprises people. Many propellant aerosol sprays contain additives that polymerise onto nonstick surfaces at air-fryer temperatures, leaving a sticky, brownish film that will not wash off and that gradually ruins the coating's release. Use a pump-style oil mister, or toss food in oil in a bowl before it goes in the basket.

Smells, smoke and stubborn residue

Smoke during cooking usually means fat has pooled in the bottom of the drawer beneath the crisper plate — common with bacon, sausages and well-marbled meat. Pour a tablespoon of water into the drawer under the plate before cooking fatty food; it stops the fat reaching smoke point. Clean the drawer as soon as it cools.

Lingering smells respond to a paste of bicarbonate of soda and water left on the affected surface for ten minutes, then wiped off. Half a lemon rubbed over the basket and rinsed also works, and is gentler than anything sold specifically for the job.

Baked-on carbon on the crisper plate holes is best dealt with by soaking the plate in hot soapy water and then working the holes with a soft-bristled brush — an old toothbrush is ideal. If airflow through the plate is blocked, crisping suffers, which is one of the causes in our not-crisping troubleshooter.

When the basket is finished

Coatings do not last forever, and there comes a point where the honest answer is replacement rather than cleaning. Flaking, bubbling or bare metal showing through means the basket is at the end of its usable life. Many manufacturers sell replacement baskets, which is far cheaper than a new machine and worth checking before you replace the appliance — one of the reasons parts availability features in our brand guide. If the machine itself is old too, the current picks are here.
