I would like some help in cleaning the porcelain grates on my whirlpool gas range...the owners manual says not to put them in with the self cleaning cycle but i have tried every degreaser imaginable, copper scrubbing pads, Brillo, Soft Scrub, you name it and nothing does it. After one use cooking, and I clean while I cook, it's just baked on and annoying as can be...any suggestions?
