My buddy Craig swore I could clean my grill with an onion half and nothing else
So last Saturday I'm at a cookout at my place and the grill grates are absolutely caked. Like a year of buildup caked. Craig, who claims to be a grill master, grabs a white onion, cuts it in half, stabs it with a fork, and says 'just rub this on the hot grates for a few minutes and it'll look brand new.' I was skeptical but hey, free advice. I tried it. All that happened was the onion turned black and fell apart, leaving little burnt onion bits stuck to the gunk. Then I had to scrape everything off anyway with a wire brush which took twenty minutes. Has anyone else fallen for this? Or does this actually work on some grills and not others?
