I can't speak about cleaning the window model, as mine is older without the window. Most of the SMF MES owners have learned that the residue left behind on the inside cabinet is now a well seasoned unit, so we leave it. If anything gets over greasy or starts caking up thick, then wipe it down with hot moist cloth, I don't use soap, I'm only trying to get the heavy stuff off. Generally I wipe out the bottom and the corners, plus around the drain hole. I also wipe the door sill on both the door and the cabinet, and keep the rubber gasket clean. I have used soap in the bottom if the grease was heavy, and rinse thoroughly. For the racks, I wash them in the sink with hot water dish soap and if anything is stuck on I use a brillo pad, then put them in the dishwasher. We have a new dishwasher that really does a great job. I have rib racks, which after my son's wedding rehearsal dinner Q I left sitting outside for two weeks untouched, they had some heavy caked on stuff. As a test on the new dishwasher, I just threw them in without pre-scrubbing, man was I surprised the racks came out clean. So now I'm going to try the main racks without pre-scrub and see how clean they come out.
