Getting them shiny is a lot of work. I did that the first couple of times with the WSM but with two grates, it took way to much time. Plus, with their size, it’s difficult to find a place to wash off. When washing, it seemed like the “greasy splatters” would get all over the clothes and kitchen. Now I just put the grates into the gas bbq, let it get to 400 – 500 degrees and spray them with Pam. The “leftovers” on the grates flame up and burn off; I then just wire brush off the grates, wipe the grates off with an oiled paper towel, and then they’re ready to go for the next time. Probably takes 2- 3 minutes of my time to do it this way. . Another way is to put the grates directly over the charcoal ring when finished and do the same thing. You won’t get them shiny with this method, but it is much easier and something to think about.
