My one frog mat is laying in the garage dirty. I got along for many years without them so just bought one last summer. It does not come clean in the dishwasher, I have to use a brush on it in the sink. Most of what I cook goes on the grates, for small things like wings I like the porcelain coated perforated pans. I also have two stainless perforated pans, I use, rectangular and two cover the grate area on my Traeger. Don
