I wound up getting a RiverGrille for Christmas and it has stainless steel grates instead of the cast iron grates I thought it would have. I has wondering what would be the best way to season stainless steel grill grates. My directions say do it over indirect heat over the grill but it seems that there's no way possible. Some say after washing the grates with soapy water, put vegetable oil on them and put them in an oven at either 250 degrees or 400 degrees, do it on the grill at 250 degrees, or just spray or rub oil on the grates when you are ready to cook. Which is the best way to go? If my grill lasts longer than the stainless steel grates (I hope) I may plan to by universal cast iron grates but for now it's the stainless steel ones. This is my first grill and I'm a beginner at this.
