Rust forming inside the cook chamber or on grates.

Safety first: Wear gloves and eye protection when scrubbing rust.

• Remove surface rust: Use a grill brush or fine steel wool to scrub rust from grates and interior surfaces.
• Clean and dry: Wipe surfaces with a damp cloth, then dry thoroughly.
• Season grates: Apply a thin coat of high-smoke-point cooking oil to grates and run the grill at medium heat for 30 minutes.
• Use a cover: Protect the grill with a Rösle-fitted cover when not in use and store in a sheltered area if possible.
• Replace severely rusted parts: If grates or panels are deeply pitted, replace them with Rösle-compatible components.
