Clean Your Air Fryer Thoroughly
- Unplug the air fryer and allow it to cool completely.
- Remove the basket and any accessories, then soak them in warm, soapy water.
- Use a soft cloth or non-abrasive brush to clean the interior, especially around the heating element and fan system.

Use Liners and Racks Properly
- Place disposable liners or mesh racks to catch drips and prevent grease from reaching the bottom.
- Ensure liners do not block airflow or touch the heating element.

Adjust Cooking Settings and Maintain Proper Use
- Reduce the temperature if you notice smoking during operation, especially for greasy foods.
- Do not overfill the basket; leave space for hot air to circulate.
- Check for any food debris or grease spills during cooking and pause to clean if needed.
Additional Tips & Warnings
