Clean Your Air Fryer Thoroughly
Unplug the air fryer and let it cool. Remove the basket and tray, then wash all removable parts with warm, soapy water. Use a soft brush to scrub away grease buildup. Wipe the interior with a damp cloth, avoiding harsh abrasives. Regular cleaning prevents grease from burning and producing smoke.
Use Proper Accessories and Liners
- Place a silicone or paper liner designed for air fryers to catch drips and prevent grease buildup, but never place liners during preheating.
- Ensure food is properly arranged to avoid excess grease dripping onto the heating element.
Adjust Cooking Practices
- Avoid overfilling the basket; leave space for hot air circulation.
- Use lower temperatures if smoking occurs frequently. For example, reduce from 450°F to 400°F and monitor.
- Preheat only when necessary, and always add food after preheating.
Additional Tips & Warnings
Regularly check for grease build-up and clean immediately after cooking greasy foods. Never operate the air fryer empty or with liners during preheating, as this can cause smoke or fire hazards. Always ensure food is placed securely and adequately spaced.
