Rust spots appear inside the smoker cabinet or on racks.

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

Steps:

• Remove loose rust: Use a non-metallic scrub pad or fine steel wool to remove surface rust from racks and interior surfaces.
• Clean and dry: Wipe with a damp cloth and then dry thoroughly.
• Season interior: Lightly coat bare metal areas with high-smoke-point cooking oil and run the smoker empty at medium temperature for 1–2 hours to reseason.

Repair: Replace heavily corroded cooking racks or water pans. Avoid harsh abrasives in the future.
