Spill the beans? In the inside I just clean the grill rack by scraping with a cleaning stone and then wipe it clean with a rag. For the outside I just cover it up after it cools down. As far as the cover I will replace it periodically. As you can see I do not do much and my grill looks no worse than most I have seen. Have you tried cleaning burnt grease off stainless steel? It requires time, dedication, patience, lots of elbow grease and an abrasive cleaner. Fail to do it one time and you get so far behind you do not want to do it again. It takes a while for the inside of the lid and the rack to get cured and to produce that good taste and you do not want to interrupt the process by scrapping it clean.
