Step 2: Check for Grease or Food Residue
- Remove the basket and inspect for grease, oil, or food debris stuck on the heating element and inside the basket.
- If you notice buildup, proceed to cleaning.
Step 3: Clean the Basket and Heating Element
- Use warm water, mild dish soap, and a soft sponge or brush to clean the basket thoroughly.
- For the heating element, gently wipe with a damp cloth to remove any grease or food particles.
- Dry all parts completely before reassembling.
Step 4: Check and Use Proper Accessories
If using accessories like racks or liners, ensure they are compatible with your model and placed correctly. For example, using the ALJ 3PCS Air Fryer Oven Mesh Rack can improve airflow and reduce residue buildup.
Step 5: Avoid Using Liners During Preheating
Never place liners, such as the Cosori Air Fryer Liners or other disposable paper liners, during preheating. Liners can fly up and contact the heating element, causing smoke or fire. Always add liners after the air fryer has preheated and food is loaded.
