Smoker interior rusts prematurely, with flaking on racks and walls.

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

• Remove loose rust: Use a non-metallic scrub pad to remove flaking rust from interior surfaces and racks.
• Clean and dry: Wash with mild detergent, rinse, and dry thoroughly. Run the smoker empty at low heat to drive off residual moisture.
• Protect surfaces: Lightly coat racks and uncoated steel surfaces with a thin layer of cooking oil to inhibit rust.
• Storage: Store the smoker in a dry location with the door slightly ajar to prevent condensation.
• Replace severely damaged parts: If racks or panels are heavily corroded, replace them with Ninja-compatible parts.
