The golf car accessory includes a bag divider adapted for attachment to a golf car to separate bags placed in the golf car. A first arm extends upwardly from the bag divider and a second arm operatively connected to the first arm and extending outwardly to support a ball washer. Preferably the first arm is a telescoping arm so that the height of the ball washer is adjustable. Preferably the second arm is also a telescoping arm so that the horizontal position of the ball washer can be adjusted.
