Abstract: A truck mop for cleaning the difficult to reach areas of a pick-up truck, or similar motor vehicle, such as the area between the cab and the cap of the pick-up truck and a method for using the truck mop. The truck mop includes a plate or support body with sponges secured to either side of the plate. The support body and sponge combination has a sufficiently large surface area to effectively clean the cab and cap of the pick-up truck, and a small enough thickness to allow the device to fit between the cab and the cap of the pick-up truck. The support body is attached to a handle of sufficient length to allow the cab and the cap to be sufficiently cleaned.
