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 the food does not stick to the grill when you use weber grill spray, cleaning up is a whole lot easier.
