The Weber Q and grill grate cleaner is a 2-in-1 cleaner. Not only can you easily clean grill grates and Weber Q grills, but also the Flavorizer Bars on your Weber grill. The cleaner thoroughly removes almost all dirt that has accumulated on the grill and grill grate. To clean, simply spray the affected areas and let the cleaner sit for a short time. Then, wipe them down with a cloth or, for tougher residues, use a soft brush (e.g., with brass bristles). For stubborn dirt, simply repeat the treatment.
