Just got an extra large egg and loving it. Made ribs first day and they were the best ribs ever. But I got barbecue sauce all over my plate setter and am having trouble getting it off. It's kinda burnt on and the manual says just use water and not soap. Not having much success in getting it clean Any ideas or should I just not worry about it. Also can I set a metal baking sheet on top of plate setter to catch drippings and prevent a reoccurrence or will this harm the plate setter Also want to cook a 3 lb chicken today. Will use direct heat and just throw the bird onto grill. I am thinking 400-425 degrees. Any suggestions.
