Abstract
A hydrogen peroxide point of use wetted wiper system includes a packaging with a first, a second, and a third compartment, wherein the separate compartments are mergable. Wipers are disposed in the third compartment. Disposed in the second compartment is dry urea hydrogen peroxide, isolated from the wipers. Disposed in the first compartment is a solvent, wherein the solvent is isolated from the wipers and the urea hydrogen peroxide. The first and second compartments can merge to form a unified compartment such that the solvent is combined with the urea hydrogen peroxide at a point of use to form liquid 6% hydrogen peroxide solution. The unified compartment then merges with the third compartment such that the liquid hydrogen peroxide wets the wipers. The liquid hydrogen peroxide concentration and amount is proportional to the wiper absorptive capacity, number, size, and degree of desired saturation.
