Step 2: Remove Food and Check for Residue
- Open the basket and carefully remove any food debris or grease spills.
- Look for darkened or burnt spots that might be causing smoke.
Step 3: Clean the Basket and Heating Element
- Wash the basket with warm soapy water or use a damp cloth for quick cleaning.
- Use a soft brush or non-abrasive scrubber to remove grease from the heating element.
Step 4: Check and Replace Liners Properly
If using liners, ensure they are suitable for air fryers and placed correctly. Never preheat with liners in place, and avoid overloading to prevent liner flying into the heating element.
Step 5: Perform a Short Test Run
After cleaning, run the air fryer empty at 400°F for 5 minutes to burn off any residual manufacturing oils or dust. This often reduces smoke during actual cooking.
