Abstract: A self-contained, fogging/atomizing sanitizer cleaning system for multiple grocery/shopping carts is manufactured and retro-fit for any size room which is used to hold shopping/grocery carts before they are distributed to consumers for use in retail stores. A stationary pumping station has a direct drive stainless steel high-pressure pump, a control panel with start stop controls, an adjustable timer, a solenoid pressure release valve, a high-pressure cut-off switch, and sanitizer storage tank. The pumping station is operatively connected to stainless steel tubing, fog/atomizing nozzle lines, stainless steel extenders, and anti-drip atomizing nozzles spray jet heads which are mounted to two walls of a preexisting cart holding room or coral with mounting hardware/channel clamps (either inside or outside the retailer).
