Thanks, Bear. I still don't see a need for it. As I've written, I wipe the inside of my smoker down. I wash the racks and the water bowl (since the outside gets covered with oily smoke residue where it wasn't foiled) after every smoke. Cooking at over 200°F will kill all nasties except perhaps for some hiding in contaminated shellfish. I've never sterilized my Weber OTS either. But then I eat an all-natural diet of dirt, rocks and grass so what do I know?:DI believe he just means take it to 275° for an hour or so. Kills a lot of Bad Stuff, and if you have a tray of pellets in there, it'll dry them out good.
