How to Clean an Air Fryer: The Complete UK Guide
If you cook three or four times a week in a compact kitchen, you already know the trade-off: brilliant crispy results, but a basket that needs attention after every session. UK owners on r/AskUK and r/airfryer consistently rank ease of cleaning alongside capacity and energy cost when choosing a model — and the same priorities apply once the machine is on your worktop.
This guide walks you through safe, effective cleaning for basket-style and oven-style air fryers, with UK-specific tips on limescale, dishwasher use and when non-stick coatings need gentler care.
Why Regular Cleaning Matters More Than You Think
Leftover oil does not just smell — it carbonises on heating elements and reduces airflow. That is when chips go soggy and chicken skin fails to crisp. Reddit threads about energy bills also highlight a quieter benefit: a clean basket heats faster, so you run the machine for fewer minutes per meal.
For multi-function units like the Cosoriaf Pro Air Fryer Oven, which combines a 4-slice toaster with an XL air fryer, keeping both cavities grease-free protects the non-stick surfaces and avoids smoke when you switch from toast at breakfast to air-fried dinner.
What You Need Before You Start
- Warm water and washing-up liquid (avoid abrasive pads on coated baskets)
- Soft sponge or silicone brush
- Baking soda paste for stubborn grease
- Dry microfibre cloth
- Optional: wooden skewer or soft toothbrush for element gaps
Always unplug the unit and let it cool for at least 30 minutes. Never submerge the main housing or power base in water.
Step-by-Step: Cleaning the Basket and Crisper Tray
- Remove the basket and any separator tray. Shake loose crumbs into the bin.
- Soak in warm soapy water for 10–15 minutes if grease is baked on.
- Scrub gently with a non-scratch sponge. For stuck-on residue, apply a baking soda paste, wait five minutes, then wipe.
- Rinse, dry thoroughly and leave to air-dry before reinserting — moisture plus heat causes steam burns.
Check your manual before using a dishwasher. Many Cosori-style baskets are top-rack safe, but repeated dishwasher cycles can shorten coating life over years of daily use — a concern raised frequently in UK appliance forums.
Cleaning the Interior and Heating Element
Wipe the inside walls with a damp cloth and a drop of washing-up liquid. For oven-style air fryers with exposed elements, use a soft brush to dislodge grease — never metal tools.
If you notice white chalky deposits in hard-water areas (common across much of England and Wales), wipe with a cloth lightly dampened with equal parts water and white vinegar, then rinse and dry. This is especially useful for combined toaster-air-fryer units where crumbs and steam share the same chassis.
Deep-Clean Schedule for UK Households
| Frequency | Task |
|---|---|
| After every use | Empty crumbs, wipe basket, check for pooled oil |
| Weekly | Wash basket and tray, wipe interior walls |
| Monthly | Inspect element or rear fan grille, deodorise with bicarbonate |
| Quarterly | Check door seals (oven models), descale if limescale visible |
Common Mistakes UK Owners Make
- Metal scourers on non-stick — scratches harbour grease and can release coating over time.
- Reassembling while damp — causes steam, smell and uneven cooking.
- Ignoring the area under the basket — drips collect and smoke on the next cycle.
- Harsh oven cleaner sprays — can damage plastics and rubber seals on countertop units.
When Cleaning Is Not Enough
If the non-stick surface is flaking, warped or rusting through, no amount of scrubbing restores safe performance. Replacement baskets exist for many Cosori models (see our replacement basket guide), but if the main unit smells of burning plastic or trips your RCD, retire it.
Upgrading to a fresh 10-in-1 model such as the Cosoriaf Pro Air Fryer Oven (£159.94, free UK delivery, 30-day returns) gives you new baskets, a 4-slice toaster and oven-style capacity without claiming worktop space for three separate appliances.

Frequently Asked Questions
Can I put my air fryer basket in the dishwasher?
Many baskets are top-rack dishwasher safe, but hand-washing extends non-stick life. Check the manual for your exact model.
How do I get rid of the plastic smell on a new air fryer?
Run one or two empty 10-minute cycles at 180°C in a ventilated kitchen. Wash removable parts before first real cook.
How often should I deep-clean my air fryer?
Light wipe after every use; full basket wash weekly; interior deep-clean monthly or sooner if you cook fatty foods daily.
