Check and Remove Excess Grease
Grease accumulation is a common cause of smoking. Carefully inspect the heating element and interior surfaces. Use a soft cloth or paper towel to wipe away any grease or food residue. For stubborn spots, a mixture of vinegar and water can help loosen buildup. Regular cleaning after each use significantly reduces smoke risk.
Use Liners Correctly
- Always place liners after preheating, not during.
- Ensure the liner is weighted down with food to prevent it from flying up.
- Use the recommended size (about 7.9 inches for COSORI liners) to fit snugly in the basket.
- Avoid lining the basket during preheat to prevent the liner from touching the heating element and causing smoke.
Avoid Overfilling and Spills
Overfilled baskets can cause grease and food to spill over, which then drips onto the heating element and causes smoke. Follow recommended fill levels and shake or turn food as needed to promote even cooking without overflowing.
Perform Regular Maintenance
Consistent cleaning and inspection help prevent smoke. Consider using accessories like the ALJ 3PCS Air Fryer Oven Mesh Rack to keep food elevated and prevent drips, or use high-quality liners like the Cosori Air Fryer Liners for easy cleanup and protection.
