Step-by-step fix
1. Let it cool and unplug
Never clean the air fryer while hot or plugged in.
2. Clean removable parts
Wash the basket, tray and drawer with warm water and dish soap or according to the manual.
3. Wipe visible interior residue
Use a damp cloth only where the manual allows. Avoid soaking or spraying the appliance body.
4. Remove old grease film
Grease film holds odor. Soak removable parts briefly if the manual permits.
5. Prevent recurring smell
Avoid overcrowding, clean crumbs after greasy foods, and dry all parts before storage.
Important warning
Do not immerse the appliance body in water. Stop using it if you smell electrical burning, see smoke from the appliance body, or notice damaged cords.
Prevention routine
- Fix the source before adding fragrance, sprays or candles.
- Keep wet areas dry and ventilated.
- Clean tools and filters, not just visible surfaces.
- Use the smallest effective amount of cleaner to prevent residue buildup.
- Recheck the same area 24 hours later; recurring odor means the source is still active.
