These charger plates are great for formal events like receptions and banquets. To use them, simply place them under your regular dinner plates for a decorative touch. They pair perfectly with our placemats. When it comes to cleaning, don't put them in the microwave or dishwasher. Before first use, hand wash them in warm, soapy water, rinse well, and dry with a lint-free cloth. For a better finish, you can clean them with a 50/50 vinegar and water solution, let it stand for a few hours, then rinse and dry. Also, since they're made overseas in large quantities, clean them to remove any dust before use.
