I saw an ad on tv for Pam where this guy was spraying the rack on his gas grill. It was as silver and clean as can be. I grilled some wonderful flank steak today and realized that mine was charred black. I usually heat up the grill and then when it's hot, I use a wire brush to "scrape" the rack before I put on the meat. Does anyone have a shiny clean rack on their grill? I mean, it made me wonder...do I have to grodiest grill on the planet? Everything tastes great!
