How often you clean your cooking grates depends on how often you're grilling, but we do advise cleaning them every time you use your grill.
Preheat the grill on high for 15 minutes, with the lid closed, and then brush the grates clean with a Stainless Steel Grill Brush.
For a deeper cleaning, use the cooking grate cleaner and scrubber pads found in our Weber Maintenance Kits, after the grill has completely cooled.
