Should Your Clean Your Grill Grates

When I say “clean the grates” on my bbq grill or smoker, I don’t mean take them inside and wash with soapy water or stick in the dish washer. Should You Scrape Your Grill Grates. I asked the question in the BackYard Smokers BBQ Facebook group a couple of years ago and the overwhelming response I got was that most people at least scrape the grill grates off before cooking anything on it.
