Microwave cavity paint is peeling or rust is visible inside.

Safety: Unplug before working inside the cavity.

• Step 1 – Clean and dry: Thoroughly clean the cavity and dry it. Remove loose paint flakes.
• Step 2 – Treat rust: Lightly sand small rust spots to remove loose corrosion. Wipe clean.
• Step 3 – Touch-up paint: Apply microwave-safe cavity touch-up paint to small bare metal areas, following the product instructions.

Extensive rust or holes in the cavity can compromise safety; in such cases, replacement of the microwave is usually recommended.
