I have done a lot of searching this forum for tips on cleaning an MES. I always run into the same 2 sides. Don't clean the inside, just the racks, water/drip pan because it is seasoned. The other side is to clean it to avoid Mold. I don't want to ruin my smoker with mold but I am very into the idea of having a seasoned smoker and less clean up. Will not cleaning my smoker cause mold and ruin the machine? If so how long until mold will grow and then there is no turning back? Does the environment I keep it in have anything to do with mold growing or how quickly it grows? Right now my Smoker has been left outside with a cover on it. I will start storing it in the garage though. I did my first smoke 6 days ago. because of my work schedule I am only able to clean the window and insides today. Racks will go in dishwasher or I will use oven cleaner in a garbage bag. The Window I am going to try the wet paper towels with ashes from charcoal to wipe it off. There are a few drops of grease on the chip loader so I am concerned about that and getting it clean. Other than that do I really need to clean it...or be concerned about mold? Thank you!
