Rust forming inside the cook chamber, on grates, or in the hopper.

Safety first: Ensure the grill is cool before cleaning rusted areas.

• Remove surface rust: Use a grill brush or fine abrasive pad to remove loose rust from grates and interior surfaces.
• Season grates: Apply a thin coat of high-smoke-point cooking oil to grates and heat the grill to bake in a protective layer.
• Empty hopper: Do not leave pellets in the hopper for long periods, especially in humid conditions. Empty and store pellets indoors.
• Use a cover: Protect the grill with a Broil King cover when not in use.
• Replace severely rusted parts: If grates or internal panels are heavily pitted, replace them with OEM parts.
