Step 2: Check for Residue and Food Debris
Open the basket and look for food particles, grease, or oil build-up. Remove any visible debris with a soft cloth or paper towel.
Step 3: Clean the Basket and Interior
- Use warm water, mild dish soap, and a non-abrasive sponge to thoroughly clean the basket, tray, and interior surfaces.
- Pay special attention to corners and heating elements, removing any grease or food residue.
Step 4: Remove Excess Oil and Oil Spills
If you notice excessive oil, wipe it down carefully. Using a paper liner (such as the Cosori Air Fryer Liners) can help prevent oil accumulation on the basket and make cleanup easier in future uses.
Step 5: Check and Replace Liners Properly
- Ensure liners are placed correctly, avoiding preheating with liners in the basket, which can trap grease and cause smoke.
- Always place enough food on liners to prevent them from flying up and touching hot elements.
Step 6: Inspect Heating Element and Fan
Look for any signs of burnt residue or debris on the heating element and fan. If so, carefully clean with a soft brush or cloth. Do not use water directly on electrical components.
Step 7: Prevent Future Smoking
- Regularly clean your air fryer after each use to prevent grease build-up.
- Avoid overloading the basket to ensure proper airflow and cooking.
- Use compatible liners like the Cosori Air Fryer Liners to reduce residue.
