Step 2: Clean the Inside Thoroughly
- Remove the basket and any accessories. If you use liners, remove them carefully to avoid spreading residue.
- Wash the basket, tray, and accessories with warm, soapy water. Use a soft brush or sponge to remove grease and food particles.
- Wipe the interior, including the heating element, with a damp cloth. Be gentle to avoid damaging the heating coil.
- Dry all parts completely before reassembling.
Step 3: Check and Remove Excess Grease
Inspect the heating element and surrounding areas for grease buildup. Use a soft-bristled brush or a cloth to gently scrub away any greasy residue. Excess grease can vaporize and cause smoking during operation.
Step 4: Use Proper Liners and Loading Techniques
If using paper or silicone liners, ensure they are placed correctly without blocking airflow. Never place liners during preheating, and avoid overfilling the basket to prevent grease from pooling and smoking.
Step 5: Run a Short Test Cycle
After cleaning, run the air fryer empty at a high temperature (around 400°F) for 5-10 minutes. This helps burn off residual manufacturing oils or cleaning products. Watch closely for smoke or unusual smells.
