Yeah, I've seen people on here with spotless Grates. I've tried soaking them - then scrubbing - then putting in the dishwasher - still lots of black on them. HOW THE HECK DO YOU GUYS GET YOUR GRATES SO DARN CLEAN?!?!?! I can't seem to figure it out.... </div></BLOCKQUOTE>
You need to start with new grates. Keeping them clean is easier than getting them clean after a number of cooks. Then, you need to spray them with Pam (or whatever brand), then soak them and scrub them after each and every cook. I wouldn't put them in the dish washer or put them on a hot grill. That will basically turn a stain to carbon and you'll not get that off without major scrubbing or something like oven cleaner.
Another thing you can do is not let it bother you. That black is not going to hurt a thing. If you scrubbed them and put them in the dishwasher, they are as clean as they need to be to cook on.
