Martial arts mats are extremely easy to clean since water cannot pass through the surface. If your mat appears dirty, we suggest using a rag or synthetic mop with a mild soap-and-water solution for stuck-on stains and a broom for any large debris. While there is not a specified number of times for sanitizing your mat, disinfecting your mat after every use, be it practice or a match, is highly recommended. Clearing it from any dirt, or bacteria is crucial when maintaining your mat for a long period of time.
