The Cuisinart Triple Nylon Bristle Grill Brush cleans grills cold and cleans grills fast. It is 3 brushes in 1 & cleans faster than a traditional brush. It features nylon bristles designed to use once your grill has cooled. They will go to task cleaning up grill grime and are safe to use on all types of grill grates. The bristles are firmly rooted in the brush, but sometimes during normal grilling bristles can dislodge. In the event that occurs, our red bristles are easy to spot for added safety. The 90 Degree angles of each brush allow you to clean even the hardest to reach places and apply more cleaning leverage.
