Step 2: Remove and Clean the Basket and Interior
- Take out the basket and any accessories, such as racks or trays.
- Wash the basket, tray, and accessories with warm, soapy water, using a non-abrasive sponge to remove grease and food residue.
- Wipe down the interior of the air fryer using a damp cloth. For stubborn spots, use a little vinegar or a mild degreaser safe for appliances.
Step 3: Check and Replace Liners or Accessories
- If you’re using disposable liners, ensure they’re not overcrowded or folded, which can trap grease.
- Replace any damaged or thickened liners with appropriate, non-flammable options like the Cosori Air Fryer Liners or Air Fryer Paper Liners.
- Avoid placing liners during preheat or without food to prevent them from flying up and causing smoke.
Step 4: Clear Out Grease and Food Debris
Inspect the heating element and interior for grease or food particles. Use a soft brush or cloth to gently clean any buildup. A toothbrush can help reach tight spots. Avoid harsh abrasives that could damage components.
Step 5: Prevent Future Smoke
- Always preheat the air fryer without food or liners to avoid trapping debris.
- Use minimal oil to reduce grease accumulation.
- Regularly schedule deep cleaning after every few uses.
