Step 2: Remove and Clean the Basket and Tray
- Carefully remove the basket and any accessories.
- Wash them with warm, soapy water or place in the dishwasher if compatible.
- Check for grease or food residue and scrub thoroughly.
Step 3: Inspect the Heating Element
Look inside the air fryer for any visible grease, food debris, or damage on the heating element. Use a soft brush or cloth to clean off any buildup. Do not use abrasive materials.
Step 4: Check for Excess Grease or Food Residue
Excess grease can drip onto the heating element causing smoke. Use a paper towel or cloth to wipe down the interior, especially around the heating area and fan.
Step 5: Use Proper Liners and Avoid Overfilling
Place disposable liners, like the Cosori Air Fryer Liners, to catch drips and reduce grease contact. Do not overfill the basket—leave space for air circulation and prevent food from touching the heating element.
