1) If you do not have a grill brush try this method for cleaning: Crumple a sheet of heavy-duty aluminum foil until it’s the size of a softball and pick it up between locking grill tongs. The tongs will serve as the handle. Holding the tongs onto the ball of foil, and brush away.
2) Burgers will puff up in the middle as they cook, making the tops rounded and awkward for keeping the toppings in place. To avoid this, press a little indentation into the top of each raw patty with your thumb or the back of a spoon. Then, when the center pushes up, the top of each burger will be relatively level.
3) Don’t use a water bottle to extinguish fire flare-ups. When water lands on the hot-cooking grates and flames, it could splatter, causing burns, or crack the porcelain-enamel finish of the grill. The quickest way to extinguish fire flare-ups is to close the lid on the grill. The lid will reduce the amount of oxygen that feeds the fire, thus limiting or snuffing out the flare-ups.
