Obviously you're not supposed to do this, but I know sometimes idiots will burn trash like plastic wrappers and Styrofoam on fire rings. When I come camp on the same site after them, am I putting my health at risk when I cook in a fire ring then? I'm concerned about the toxic ash that could be deposited from burned trash on the grate and in the pit itself. Is there anything I can do to keep myself and my loved ones safe? How best can I clean out the pit and the grates?
