Step 2: Remove Food and Clean Residue
- Open the basket and remove any remaining food.
- Use a damp cloth or soft sponge with mild detergent to wipe away grease and food particles from the basket, heating element, and interior surfaces.
- Pay special attention to corners and the heating element area where grease can accumulate.
Step 3: Check and Remove Liners
If using disposable liners, ensure they are placed correctly—never during preheating or without food on top. Remove any liners that have shifted or appear damaged.
Step 4: Inspect and Clean the Heating Element
Carefully inspect the heating element for grease or food residue. Use a soft brush or cloth to clean it gently, taking care not to damage it. This step prevents smoke caused by burnt residue.
Step 5: Prevent Future Smoking
- Use appropriate liners, like Cosori or compatible non-stick, food-grade liners, and avoid preheating with liners in place.
- Regularly clean your air fryer after each use to prevent buildup.
- Do not overfill the basket, which can cause grease to spill and smoke.
