Maintenance and Cleaning

Interior Cleaning

• Regularly clean the oven interior with a damp cloth and mild soap.
• For stubborn food splatters, place a bowl of water with lemon slices inside and microwave for a few minutes to loosen residue, then wipe clean.
• Remove the glass turntable and roller ring for cleaning. These parts are dishwasher safe.
