Step 2: Clean Grease and Food Residue
- Remove the basket and tray, and wash them with warm, soapy water. Pay special attention to any grease or food residue.
- Use a soft brush or sponge to scrub stubborn spots, especially around the heating element.
- Dry all parts thoroughly before reassembling.
Step 3: Check and Remove Liners or Accessories
If you’re using disposable liners or accessories, ensure they are properly placed and not touching the heating element. Never preheat with liners inside, as they can ignite or cause smoke.
Step 4: Inspect the Heating Element
Look for any accumulated grease or food splatters on the heating element. Carefully wipe with a damp cloth or a soft brush. Avoid abrasive cleaners that can damage the surface.
Step 5: Adjust Use and Settings
Ensure you’re cooking at appropriate temperatures (not exceeding 450°F). Use the Shake Reminder feature if available, to prevent food from burning or splattering that could cause smoke.
