The other secret to keeping food from sticking to the grate is to oil or grease it first (a well-oiled grill grate also gives you better grill marks). You have a choice of three greasing techniques: using an oil-soaked paper towel or rag, a piece of bacon or beef fat, or a can of spray oil. When you oil the grate with a paper towel or rag, you give it one last cleaning. If you are working on a large industrial-size grill, tie a tightly folded clean dish towel or washcloth to the end of a pole and use it for oiling. Be sure the grate is very hot before oiling it.
