The Microplane Zester/Grater features a premium soft-touch handle and non-scratch end tabs grates even the hardest Parmesan Reggiano as well as other hard cheeses into fine lacy wisps. It's also wonderful for effortless citrus zesting to add natural flavors to a lemon creme brulee or a basic vinaigrette. We recommend rinsing your grater in warm water immediately after each use. Remove trapped particles from the non-sharp side whenever possible. To remove trapped particles on the front, first soak the tool in warm water and then use a cleaning brush to stroke in the same direction as the teeth.
