Clean the Air Fryer Thoroughly
- Unplug the air fryer and let it cool completely.
- Remove the basket and tray, then wash them with warm, soapy water.
- Use a soft brush or sponge to scrub any greasy spots or food buildup.
- Dry all parts thoroughly before reassembling.
Check and Manage Oil and Food Placement
- Ensure food is dry before placing in the basket to prevent excess splattering.
- Use minimal oil; excessive oil can cause smoke during cooking.
- Place food in a single layer for even cooking and less splatter.
Adjust Cooking Settings
If smoke persists, try lowering the temperature slightly and reducing the cooking time. Using a lower setting can prevent overheating and reduce smoke generation.
Use Proper Accessories and Liners
When using liners or racks, ensure they are placed correctly and not during preheating. Consider using accessories like the ALJ 3PCS Air Fryer Oven Mesh Rack to promote even airflow and reduce residue buildup.
