Patent ID: 8021610

Claim:
A process for reducing the microbial content in a confined area having an environment selected from the group consisting of vehicle cabs, vehicle seating areas, dishwashers, refrigerators, freezers and liquid circulation systems comprising providing at least two particulate reagents that react in the presence of water to form I 2 in the confined area to provide a concentration in aqueous material in the environment of at least 5 parts per million I 2 /water, at least one of the at least two particulate reagents having a coating thereon that prevents atmospheric moisture from causing more than 5% of the reagents to react with each other to form I 2 when exposed for twelve hours to atmospheric moisture while particles containing the at least two reagents are in contact with each other in the environment, adding water to the two particulate reagents while they are in the confined area, and allowing the formed iodine to reduce microbial content within the confined area and throughout the environment of the confined area.
