The present invention includes multifunctional compositions, methods and binding systems to provide disinfecting and deodorizing coatings for hard and soft surfaces, inorganic and organic solid surfaces and particulate media and other related substrates, including human and animal skin and skin lesions; to provide neutralizing functions for malodors generated by both human, animal and industrial fluids and solid wastes; and to provide neutralizing and degrading functions for nuisance and noxious chemicals. The present invention provides compositions and methods for producing disinfecting, oxidizing and enzyme-inhibiting fluids enabling preparation of durable, stable biocidal and deodorizing coatings and media which can be widely used for biological agent control, prevention and elimination of odors, and degradation of noxious agents susceptible to chemical oxidation, and which take forms that are inoffensive to users and offer high convenience.
