A quick tip from Spike Mendelsohn, as seen on Rachael Ray. To clean up your grill grate(s) – anytime, but especially now – use a large onion cut in half to scrub! It will not only break up the crust that we usually leave behind, it will help season and flavor your grill. If that didn’t quite clean it up, follow with a halved lemon or two… Then when you’re ready to grill, dip a wad of papertowels in olive oil, and using tongs rub the heated grates to help prevent sticking. Hmmm… onion, lemon, and olive oil? Sounds like anything that follows is going to be special
