Clean the Air Fryer Thoroughly
- Remove the basket and any accessories, such as racks or liners.
- Wash the basket and accessories with warm, soapy water or in the dishwasher. Use a non-abrasive sponge for stubborn grease.
- Wipe down the interior with a damp cloth to remove grease and residue.
- Dry all parts completely before reassembling.
Address Grease and Food Residue
Grease buildup is a leading cause of smoking. Regular cleaning prevents this. If residue persists, consider applying a vinegar solution or specialized appliance cleaner for stubborn spots. Always ensure the appliance is unplugged and cooled before cleaning.
Use Proper Accessories and Liners
- Use high-quality, heat-resistant liners like Cosori Air Fryer Liners to prevent grease from reaching the basket.
- Ensure liners are properly placed and do not cover the entire basket, allowing airflow.
- Use racks like ALJ 3PCS Air Fryer Oven Mesh Rack for even cooking and to prevent food from sticking to the bottom.
Prevent Future Smoking
- Always preheat the air fryer without food for a few minutes to burn off any residual grease.
- Avoid overfilling the basket to allow proper airflow and prevent grease from splattering.
- Regularly clean the appliance after each use—grease and food residues build up over time.
