Rust forming on interior surfaces, racks, or chip tray.

Safety first: Ensure the smoker is unplugged and cool before cleaning.

• Remove rust: Use a non‑metallic scrub pad or fine steel wool to gently remove surface rust from racks and trays.
• Clean and dry: Wash affected parts with warm soapy water, rinse, and dry thoroughly.
• Season interior: Lightly coat interior steel surfaces (not heating element) with a thin layer of high‑smoke‑point cooking oil and run a short seasoning cycle.
• Replace severely rusted parts: If racks or trays are heavily pitted, replace them with Cuisinart replacements.
