The Cuisinart Onion Grill Cleaner & Seasoner is a bristle-free alternative for cleaning your grill. Offering a safer way to clean your grill! Wire bristles can break off while cleaning and get stuck to your grill cooking surface. Simply cut a white onion in half and firmly place into the Onion Grill Cleaner; with grill gloves on, rub it over the still-warm grill grates. While it cleans it will also help season your grill grates, filling the air with a savory aroma.
