To clean the interior chamber of the smoker let it cool completely. Remove the racks, water pan, drip tray and smoker box. Brush any particle buildup downward toward the bottom of the smoker. Sweep all residue out of the chamber.
HOT TIP: The interior of the cooking chamber will continue to darken with use and will not return to a shiny silver color with scrubbing. This darkening inhibits rusting and actually improves the performance of the infrared cooking system.
