Abstract
New methods are disclosed for decontaminating surfaces and enclosures that avoid problems such as salt deposits, corrosion and condensation that accompany the use of known methods. The methods involve the use of chlorine dioxide solutions prepared by passing dilute chlorine gas over solid granular sodium chlorite to produce chlorine dioxide gas which is then collected to form a solution with very low levels of impurities. The chlorine dioxide gas can be introduced into an enclosure and used to disinfect a portion of the contents of the enclosure.
