Billy Smoker units are built to last with the right care. Mild Steel units: Painted metallic black (industry standard finish). For outdoor or exposed installations, a covered area is recommended. Re-season the firebox periodically by lighting a small fire to burn off surface moisture. Stainless Steel units: Handles both covered and uncovered environments with minimal corrosion. Wipe down with a damp cloth after use. Avoid abrasive cleaners. General: Remove ash regularly to maintain airflow and cooking performance. Check flue and spigot connections periodically. Keep the unit dry when not in use.
