Microwave cavity paint is peeling or rust is visible inside.

Safety first: Unplug the microwave before cleaning or painting.

• 1. Clean and dry: Remove loose paint and rust flakes with a non-metallic scraper and fine sandpaper. Wipe clean and dry thoroughly.
• 2. Touch-up paint: Use only microwave-safe cavity touch-up paint recommended for appliances. Apply thin coats and allow to cure fully as per instructions before using the microwave.
• 3. Prevent recurrence: Avoid abrasive cleaners and promptly wipe spills.

Note: Severe rust near the waveguide or door seal may compromise safety; consult a technician.
