The StepWell mat provides an all-in-one solution for safely sanitizing shoes. It features a 2' x 3' well that holds an abrasive insert and your preferred liquid sanitizer, followed by a 3' x 5' carpeted section to help remove any excess moisture from shoes, reducing the likelihood of slips following sanitation. The insert serves as a splash guard and helps dislodge any dirt or debris from the bottom of shoes so the fluid can reach the entire sole surface. Each mat includes one insert, additional inserts are available in packs of four. Well holds one insert and approximately 84 oz. of sanitizing solution (not included). Compatible with most sanitizing/disinfecting solutions. Works best with quaternary or hydrogen peroxide sanitizing solutions.
