4. Maintenance and Cleaning
4.1 Cleaning the Cooking Drawer and Accessories
The 6.6 L cooking drawer, removable separator, and two crisper plates are all non-stick and dishwasher-safe. For best results and to prolong the life of the non-stick coating, hand washing with warm, soapy water and a non-abrasive sponge is recommended.
4.2 Cleaning the Main Unit
Wipe the exterior of the main unit with a clean, damp cloth after each use. Do not use abrasive cleaners or scouring pads. Never immerse the main unit in water or any other liquid.
4.3 Storage
Ensure the appliance is cool and clean before storing. Store the air fryer in a dry place, preferably in its original packaging or a protective cover.
