Microwave cavity shows rust spots or peeling paint, especially on the floor or near the door.

Safety note: Exposed rust can lead to arcing and further damage if not addressed.

• Clean and dry: Thoroughly clean the cavity and dry it completely.
• Sand lightly: Lightly sand rust spots to remove loose material. Avoid breathing dust.
• Touch-up paint: Apply microwave-safe cavity touch-up paint to cover bare metal. Allow to cure as per instructions before use.
• Replace tray or accessories: If the glass tray or rack caused chipping, inspect and replace them if damaged.
