Process for disinfecting article with device dispensing chlorine donor and chlorine acceptor

A process for disinfecting an article of manufacture in need of disinfecting, which process comprises placing the article of manufacture in an environment consisting essentially of a dispensing device in contact with an aqueous liquid, which dispensing device consists essentially of a polymeric body consisting of two compounds dispersed in the polymeric body, consisting of a first unreacted compound comprising chlorine that is a chlorine donor and a second unreacted compound comprising nitrogen that is a chlorine acceptor, which first donor compound and second acceptor compound on their release by at least one of the process of diffusion, the process of osmotic bursting and the process of erosion, from the dispensing device in the aqueous liquid contact and react with each other in stoichiometric ratio and produce a biocidal compound comprising chlorine for disinfecting the article of manufacture.
