Abstract
This invention relates to extend the benefits of using hypochlorite compounds such as sodium hypochlorite to clean and disinfect articles while reducing or eliminating the side effects of treating an article with a strong oxidant material. The invention relates to a single step process involving mixing of precursor compositions of a suitable hypohalite or hypohalous acid with a solution of a reducing agent. Optionally a buffer may be present in either or both precursor compositions, such that at time of use such active hypohalous acid concentration in the resulting aqueous mixture remains at a sufficient activity level to effect one or more desired benefits against a target substrate for a desired period of time. The oxidant is substantially consumed by reaction with the reducing agent after the time needed for achieving the desired benefit has passed.
