The Virkon Disinfection Mat keeps contaminants out of the greenhouse by cleaning your boots and shoes on the mat before entering. This disinfection mat can be used anywhere shoes and boots need to be disinfected, reducing the risk of disease spreading into sensitive work areas. Easy to use: pour 12 L of Virkon disinfectant into the mat before use. The mat's sides and bottom are sealed to contain the disinfectant. While standing on the mat, the disinfectant will well up around your boots. Simple to wash off, drain or refill.
