Clean the Air Fryer Thoroughly
- Unplug the air fryer and allow it to cool completely.
- Remove the basket and tray, then wash them with warm, soapy water or in the dishwasher.
- Wipe down the interior, heating element, and door seal with a soft cloth dipped in a vinegar-water solution to remove grease.
Address Grease and Residue Buildup
Use a non-abrasive brush or sponge to scrub stubborn residue. Avoid harsh chemicals that may damage the surface. Regular maintenance prevents future smoking issues.
Proper Use of Liners and Food Placement
- Only place disposable liners after preheating is complete and the basket is not empty.
- Ensure food is evenly distributed and not overloaded to prevent grease from dripping onto the heating element.
Additional Tips & Safety Warnings
