A guy at work told me about this the other day and I gave it a try. I took the racks out of my MES40 and put them in the oven and turned it to the auto clean cycle. It did smoke up the kitchen some, but the open windows took care of that. When the clean cycle was done, all the stuff on the racks had been burned off. I wiped them down and put them back in the smoker. pretty easy and worked great.
