Oven interior enamel is chipped or rusting, exposing metal underneath.

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

• Clean area: Remove loose enamel and rust with a non-metallic scraper and mild cleaner. Dry thoroughly.
• Touch-up (minor damage): For small chips, use a high-temperature enamel touch-up kit approved for ovens to seal the exposed metal and prevent further rust.
• Avoid abrasives: Do not use steel wool or harsh abrasives on the cavity in the future.
• Severe damage: If large areas of enamel are missing or rust is extensive, consult Asko service; cavity replacement may be required for safety.
