Everything you use should be cleaned & disinfected ! Difficult but the situation demands us an extra care.
Let's clean the shoes and the foot before entering our house. The mats are made of high quality rubber, with anti slippery properties. It can hold disinfecting/sanitizing solutions. It is designed in such a way that the liquid will be intact. You can either pour the liquid directly or use another mat inside for better capillary action.
The mat should be accompanied with a cotton mat to absorb excess liquid from the shoes. In ideal cases it is advised to use two rubber tray mats one with rubber mat for capillary action and one more with cotton to absorb the excess liquid.
The sanitizing solution has to be additionally purchased and you are requested to follow the manufacturer instruction for using the same in the mat.
