DON’T: try to clean the grill surface with a sponge
While you don’t necessarily want yesterday’s flavors stuck to the grill, you especially don’t want spongy crumbs or soap. If it really needs a thorough washing, which grills don’t often need, then you should detach the grate and soak it, then rinse it thoroughly as soap is actually a laxative.
DO: try to clean the grill surface with an onion
Food bits stick heartily to woven metal, whether your grill is for charcoal cooking or a bejeweled tooth façade. In order clean your grilling surface, wait until you plan to cook with it, then, once it’s nice and hot, rub a halved onion along its surface. This cuts through the grease and fat, as onions are astringent, and adds flavor to your food, as onions have, you know, flavor.
