Epai Technology introduces a multi-level sterilization solution for washing machines: Surface sterilization – targets the inner walls of the washing machine. Deep sterilization – targets rubber seals, pipes, and fabrics. Stain removal – targets clothing. These three methods use electrolytically generated hydrogen peroxide as the main sterilizing agent, adhering to the green principle of “0 consumables, 0 stimulation, 0 odor, 0 residue.”
