I foil the bottom of the smoker and the wood box, so clean up is a breeze...just remove the foil and wipe down the bottom to catch any liquid that slips passed the foil. Every couple of months, I remove the side panels and run those through the dishwasher. I clean the racks after each use by hand with hot soapy water and a brush. Maybe once or twice a year, I will scrape the inside of the box just to free up some of the build up that occurs on the side walls over time. Other than that, not much maintenance required.
