Step 2: Clean the Basket and Interior
- Remove the basket and tray, then wash them thoroughly with warm, soapy water. Use a non-abrasive sponge to remove grease and food residues.
- Inspect the interior of the air fryer, especially the heating element and fan area, for any stuck food particles or grease buildup.
- Wipe the interior with a damp cloth or soft brush. Avoid using harsh chemicals that could damage the components.
Step 3: Check and Replace Liners
If you are using liners, ensure they are appropriate for your model. Avoid preheating with liners in place, as this can cause them to burn or smoke.
Consider switching to high-quality, heat-resistant liners like the Cosori Air Fryer Liners, which are resistant to 465ยฐF and designed to prevent smoke.
Step 4: Examine and Clear the Heating Element
Look for any grease or food splatters around the heating element. If needed, gently clean the area with a soft cloth or brush. Do not use metal tools that might damage the element.
Ensure there are no obstructions or food debris that could cause uneven heating or smoking.
Step 5: Test and Prevent Future Smoke
After cleaning, run the air fryer empty at a high temperature (around 400ยฐF) for 5-10 minutes. This will burn off any residual grease or manufacturing oils.
Regular cleaning and proper use of recommended liners will help prevent smoke in future cooking sessions.
