How do I clean burnt residue from an air fryer?
Home Nura guide — category Air Fryers
Diagnosis
To clean burnt residue from an air fryer, let it cool, soak the drawer and basket in hot soapy water, then scrub with a non-abrasive sponge. A baking soda paste helps with stubborn deposits without harming the non-stick coating.
Possible causes
- Dripping grease that carbonises — drops fall to the bottom of the drawer and blacken with each cook if it is not cleaned.
- Sugary marinades or thick sauces — the sugar caramelises then burns onto the basket and bonds firmly to the surface.
- Cleaning put off between uses — layers of grease build up and harden under repeated heat.
- High temperature with no oil or suitable liner — food sticks to the basket and leaves black crusts that are hard to lift.
Recommended procedure
- 1Unplug the appliance and let it cool completely before taking out the drawer and basket for cleaning.
- 2Soak the drawer and basket for fifteen to thirty minutes in hot water with washing-up liquid to soften the deposits.
- 3Scrub with a soft sponge or brush; for stubborn residue, spread on a paste of baking soda and water and let it work.
- 4With the unit cold, wipe the inside of the housing and heating element with a well-wrung damp cloth or soft brush, without pouring water in.
- 5Rinse, dry every part thoroughly and reassemble. Never use steel wool or abrasive cleaners on the coating.
Repair or replace?
If the non-stick coating is flaking, rust appears, or a burnt smell persists after a deep clean, the appliance becomes less safe and less hygienic. In that case it is better to replace it than to keep cooking on it.

Frequently asked questions
In Europe, any air fryers bought new from an official reseller benefits from a legal conformity guarantee of at least two years (Directive (EU) 2019/771). This guarantee covers defects present at delivery, whenever they first manifest.
You can pick: European law puts the legal guarantee on the seller, not the manufacturer. In practice, a store return is usually faster, but the manufacturer can repair if the damage is out of warranty. Keep proof of purchase.
Our public methodology adds a Nura Score /10 penalty to any air fryers whose recurring failures are documented in European user feedback. A model that breaks too often never tops our charts, brand notwithstanding.
Yes, within the limits of the European "right to repair": routine maintenance tasks (cleaning, gasket replacement, calibration) never void the legal warranty. Only irreversible hardware modifications can be a problem. For a air fryers, any handling documented in the manufacturer's manual stays covered.
The directive imposes a two-year legal conformity guarantee, with a presumption of pre-existing defect during the first twelve months — the burden of proof is on the seller. For a air fryers that breaks in that window, you're entitled to free repair or replacement, no strings attached on typical use.
