Abstract: An apparatus and method is disclosed for systematically disinfecting shopping carts and other containers utilized in grocery stores by consumers to temporarily carry food items while shopping. The system consists of a hollow, inverted U-shaped housing that defines a cart passageway through which a shopping cart may be passed and disinfected. The system includes internal electrical elements, a fluid reservoir, a pump that pumps disinfecting fluid to several nozzles, a rechargeable battery, and is on wheels so that the system may be operated in an area of choosing independent from a power outlet. For disinfecting, carts are positioned in front of the cart passageway and pushed through while nozzles positioned in the cart passageway are actuated. A fine mist of disinfecting fluid envelopes all surfaces of the cart as it passes through the cart passageway, thereby sanitizing the entire surface area of the cart without accumulating residue.
