Today I saw this on the net and thought I'd do a bit about staying safe while enjoying a bit of roofless grilling. Why even have one of them? The job it does on the grill is cosmetic at best and in this case could have killed someone. If you chuck your grills on while the fire is burning in before cooking, the flames and heat will destroy any living microbe on that grill rendering it completely clean without doing anything. Just because its black, doesn't mean its dirty. Bloody hell. I bet these same people have loads of allergies and poor immune systems.
Easy as that.
