How The Great Scrape Works:
Get The Grill Hot - to start the grooving process, ensure your grill is hot (high heat allows the grooves to form quickly).
Work Back and Forth - Using slow firm pressure, pass the Great Scrape front to back on the hot grates.
Repeat - align the previously formed grooves to the grates ensuring that only ONE good set of grooves are formed. Once grooves have formed high heat is no longer necessary.
