Smoked commercially for two years. I would only scrub clean inside of smoker if wanting to loose seasoned smoker or definite smoke flavor change from one of the stronger wood chips such as mesquite. Smoking is the process of putting smoke flavors into foods not just slow cooking, otherwise why even bother with the expense of a smoker and not just a low temp. in your oven. Clean window with very light non-scouring pad and water while still warm every time. Inside walls as others have stated with credit card type item (putty knife) to get heavy layers and anything you can pull out place in dish washer for high heat clean. Racks are only place foods will be in contact and should be real clean every time ( don't forget to clean probe well otherwise placing bacteria directly into meat, this is why they also suggested to not put thermometer into meat until smoker reaches temp to kill bacteria ). Hope this helps someone. Dragonsmoke
