A system for cleaning and disinfecting a hard surface includes housing having a base and a front cover panel, an atomizer nozzle, a fluid reservoir housed within the base, and a volume of fluid contained in the fluid reservoir. The fluid may contain colloidal silver. The base of the housing may include a convex rear shell and a first flat face. The front cover panel may include a convex front shell and a complimentary second flat face. The second flat face of the front cover panel may be slidably affixed to first flat face of the base. The front cover panel may be configured to slide, relative to the base, from a first position to a second position, thereby activating the atomizer nozzle and spraying fine liquid droplets containing silver onto the hard surface. At least some bacteria on the hard surface may be killed via the silver.
