Step 2: Clean the Basket and Heating Elements
- Remove the basket and accessories. Wash them with warm, soapy water or in a dishwasher if dishwasher safe.
- Use a soft brush or cloth to clean any grease or food residue from the heating element and inside the chamber.
- Dry all parts thoroughly before reassembling.
Step 3: Check for Food Residue and Grease
Examine the inside of the air fryer for any leftover food particles or grease buildup. Burnt residue can cause smoke during operation. Remove any debris carefully and clean the surfaces.
Step 4: Use Liners Properly
If using disposable liners (like the Cosori or Air Fryer Paper Liners), ensure they are not placed during preheating and that enough food is on top to prevent them from flying up to the heating element. Avoid overfilling the basket.
Step 5: Prevent Overheating and Maintain Your Air Fryer
Regularly inspect your air fryer for signs of wear or damage. Avoid running the appliance empty or at excessively high temperatures for extended periods. Keep the interior clean and free of grease to maintain safe operation.
