Oven interior enamel is chipped or rust spots appear inside the cavity.

Safety first: Ensure the oven is cool and unplugged before cleaning or inspecting.

• Clean and dry area: Remove loose enamel and rust with a non-metallic scraper and fine abrasive pad. Clean with mild detergent and dry thoroughly.
• Touch-up (if allowed): Some manufacturers offer high-temperature enamel touch-up paint. Use only Toshiba-approved products if available, following instructions.
• Prevent further damage: Avoid metal scouring pads and do not bang heavy trays against the cavity walls.

Extensive rust or flaking enamel may require cavity replacement, which is usually not economical; consult Toshiba support.
