Abstract: Systems and methods for disinfecting/sanitizing various articles using disinfecting solutions and ultraviolet (UV) light. In one embodiment, an exemplary system includes a tank that contains a sanitizing liquid, coupled to a pipe system that includes multiple spray nozzles. A pump pumps the sanitizing liquid from the tank to the nozzles, which dispense the liquid to a disinfecting area. Some or all of the system may be mounted on a transportable mobile unit such as a trailer. In one embodiment, a portion including the tank and pump are mounted on the mobile unit and are connectable to a pipe system and nozzles that are permanently installed in a disinfecting area, such as the interior of a vehicle. Other embodiments are also possible.
