The only non-flammable grill spray. Unlike other sprays, Weber Grill Spray has a non-flammable formula (patent pending) that's safe to spray directly onto a hot grill or open flame. So, you can spray while you grill for unbeatable no-stick results. It's not a problem if you forget to spray the grill before it's heated. Plus, you can even re-spray while turning food for perfectly seared results. And because food does not stick to the grill when you use Weber Grill Spray, cleaning up is a whole lot easier. Safe to spray on a hot grill! Use on any indoor or outdoor grilling surface.
