Our 18x30 doormats make the perfect personalized gifts and feature a slip resistant backing, with a natural coir front. We use high quality cured UV Ink that helps prevent fading. The UV ink affixes directly to each fiber on the doormat. With our process there is no vinyl involved so there will be no peeling. All doormats will discolor after exposure to water and high traffic. Therefore, to extend the life of your doormat I would recommend that you keep your doormat in a dry, covered area. To clean your doormat, simply shake or vacuum away any debris. Size of the doormats: 18 x 30 x .6 (each rug varies slightly in depth) Things to note: To clean the mat, shake it out and/or sweep with a broom.
