Rust forming inside the cookbox, on grates, or on the drip tray.

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

• Clean rust: Use a grill brush or fine steel wool to remove loose rust from affected areas.
• Season grates: For cast iron or steel grates, apply a thin coat of high-smoke-point cooking oil and heat the grill to season the surface.
• Inspect coatings: If porcelain or enamel is chipped, consider replacing the affected part to prevent further rust.
• Improve storage: Use a Weber-compatible cover and store the grill in a sheltered area when not in use.
