Oven cavity shows rust spots, flaking enamel, or bubbling paint

Safety first: Do not use the oven if metal is exposed and rust is flaking near heating elements, as this can lead to further damage.

• Clean and inspect: Gently clean the affected area with a non-abrasive cleaner to remove loose material. Assess the extent of damage.
• Minor spots: For small chips away from elements, you may use high-temperature food-safe enamel repair paint following the product instructions. Allow full curing before heating.
• Severe damage: If large areas of enamel have failed or metal is heavily corroded, contact a service center. Cavity replacement is often not economical, and the oven may need replacement.
