Duo Wipes are designed specifically to apply Tristel Duo foam evenly onto a surface to be disinfected. They are made of a non-woven material and are low-linting to reduce residue of fibres on surfaces. Duo Wipes are pre-cut to prevent shedding when dispensed from the tub. The use of Duo Wipes enhances cleaning and disinfection performance by allowing effective release of the liquid disinfectant onto the surface.
