The Secret To Professional Grill Marks Every Time You Grill The only one thing that stands between a back-yard griller and professional looking results is a clean, well-oiled grill. Grate Chef® Grill Wipes are loaded with oil specially formulated for the high temperatures associated with charcoal grilling. The oil coats the grill during the cleaning process and produces the distinct grill marks on food seen in good restaurants. Grill Wipes come in a resealable package with six disposable Grill Wipes, loaded with restaurant-grade grilling oil to clean you grill, prevent sticking, and enhance grill marks.
