A composition is provided for a disinfectant fogger and cleaner for interior surfaces of confined spaces. The composition is water based and has an aqueous disinfectant containing quaternary ammonium compounds as active disinfecting ingredients, non-ionic surfactants, and a malodor absorbing agent. The composition provides a disinfectant for hard-nonporous and soft surfaces and allows for immediate occupancy and contact with a cleaned interior surface. The composition may be packaged as a ready-to-use disinfectant spray in an aerosol container with an on/off lockable discharge actuator as fine mist droplets that are dispersed onto the target surfaces for treatment.
