You also want a cooler, medium heat area of the grill to move the steaks to once they're seared and crispy on the outside. If you have enough burners and space on your grill, set them to a lower heat; if you don't have enough room, simply turn off the burner. If you are using a charcoal grill, one side should have a hot fire while the other a smaller, cooler flame.
Clean the bottom of the grill with a soapy sponge. Once all the chunks are gone, scrub the bottom with a sponge or scouring pad and soapy water to remove any built up grease or grime. Lots of drippings and food scraps tend to build up under the burners of the grill. Pay close attention to this area and clean it as much as possible to avoid corrosion.
