Step 2: Remove and Clean the Basket and Tray
- Carefully remove the basket and any accessories, such as the mesh rack if used.
- Soak these parts in warm, soapy water for about 10-15 minutes to loosen grease and food residue.
- Use a non-abrasive sponge or brush to scrub away any buildup, paying special attention to corners and the heating element area.
- Rinse thoroughly and dry completely before reassembling.
Step 3: Check and Clean the Heating Element
Inspect the heating element for any visible grease, food particles, or debris. Use a soft, damp cloth or a toothbrush to gently clean the area. Make sure no residue remains, as it can ignite during use.
Step 4: Remove and Replace Liners Properly
If you’re using disposable liners, ensure they are placed correctly and not in the basket during preheating. Avoid overloading liners with food to prevent them from flying up and touching the heating element, which can cause smoke or fires.
Step 5: Perform a Test Run
After cleaning, run the air fryer empty at 400°F for 10 minutes. This helps burn off residual grease and any manufacturing oils. Monitor for smoke during this process. If smoke persists, repeat cleaning or inspect for other issues.
