Grates or burner caps are rusting, chipping, or flaking; cooking performance may be affected.

Safety first: Ensure all components are cool before handling.

• Clean and dry: Remove grates and caps. Clean with a non‑abrasive cleaner and dry thoroughly.
• Season cast iron: For cast iron grates, lightly coat with a thin layer of cooking oil and heat in the oven at 350°F for an hour to help protect against rust.
• Avoid harsh chemicals: Do not use oven cleaner or strong caustic agents on grates or caps.
• Replace severely damaged parts: If rust or chipping is extensive, replace the affected BlueStar grate or burner cap to maintain proper flame pattern and safety.
