How to Clean an Air Fryer Properly (and How Often)

An air fryer that is never cleaned starts to smoke, smell and cook

unevenly. The good news: a proper clean takes about five minutes, and

most of it can be done without any harsh chemicals.

After every use (2 minutes)

Unplug and let it cool for 10 minutes.

Remove the basket and crisper plate.

Wash both in warm, soapy water, or put them in the dishwasher if

your model allows it.

Wipe the inside of the machine with a damp cloth to catch crumbs

and oil splatter.

Once a week (5 minutes)

• Soak the basket in warm water with a splash of white vinegar for 20

minutes if grease has built up, then wash as normal. Vinegar cuts

grease without the chemical cleaners — the same natural-cleaning

approach many UK households are switching to.

• Clean the heating element gently with a soft brush or cloth. Never

pour water into the main unit.

• Wipe the outside with a damp cloth and dry it straight away.

Once a month

• Check the air intake and outlet vents for dust and crumbs.
• Inspect the non-stick coating: if it is flaking, it is time to

replace the basket rather than keep cooking on it.

• Run the empty air fryer at 180°C for 5 minutes after cleaning to dry

it fully before storing.

Mistakes to avoid

• Never submerge the main unit in water. Only the basket and plate

are washable.

• Do not use metal scourers on non-stick coatings — they strip the

surface and make food stick worse.

• Do not use oven cleaner inside an air fryer; it is too harsh for

the coatings and leaves residues.

• Do not put it away damp. Moisture trapped in the basket causes

smells and, over time, mould.

How often should you deep clean?

If you use your air fryer daily, the weekly routine above keeps it in

good shape. For occasional use, a clean after every use plus a monthly

once-over is enough. A clean air fryer cooks more evenly, lasts longer

and never sets off the smoke alarm at dinner time.

If your current air fryer has seen better days, the Tower 4L Digital

Air Fryer (£36.79) and the COSORI Pro LE 4.7L (£82.79) both have

dishwasher-safe baskets and come with free UK delivery over £30 and a

2-year warranty at Clean Smile Home.
