Made from DuPont Nomex fabric first developed for firefighters, the Cool Touch Oven Rack Guard protects by slowing heat transfer from hot oven racks to your skin. If the Oven Rack Guard becomes dirty, simply place it in your washing machine on the gentle cycle and lay flat to dry. This product is not intended for use under the broiler, during cleaning cycles or to pull out a hot oven rack. Set of two 18-Inch guards.
