Rust forming on the interior surfaces or racks of the smoker.

Safety first: Avoid inhaling rust dust; wear gloves when cleaning.

• Remove surface rust: Use a non-metallic scrub pad to remove light rust from interior surfaces and racks.
• Clean and dry: Wipe with a damp cloth, then dry thoroughly with a towel and run the smoker empty at low heat to drive off moisture.
• Re-season interior: Lightly oil racks with cooking oil and run a seasoning cycle to protect metal surfaces.
• Improve storage: Store the smoker under a cover and in a dry location when not in use.
