Clean Thoroughly
- Remove the basket and any accessories. Wash them with warm, soapy water or dishwasher if dishwasher-safe.
- Use a soft brush or cloth to clean the heating element gently, removing any grease or food buildup.
- Dry all parts completely before reassembling.
Check and Use Proper Liners
If you use liners, ensure they are suitable for high temperatures and placed correctly. Never preheat with liners in the basket, as this can cause them to fly up and touch the heating element, causing smoke or fire risk. Use only liners compatible with your model, such as those made specifically for COSORI air fryers.
Adjust Cooking Practices
- Avoid overcrowding the basket, which can trap grease and cause smoke.
- Reduce the temperature if you notice excessive smoke, especially when cooking fatty foods.
- Use lower cooking temperatures and longer cooking times for greasy or fatty foods to minimize smoke production.
Maintain Regular Upkeep
Schedule regular cleaning after each use to prevent grease buildup. Periodically check the vents and ensure proper airflow. Consider using a small amount of oil or cooking spray sparingly to minimize residue.
