They have automated washes, but they do not work. Payment machines claim to accept credit cards, but doesn't read them, regardless of how many times you swipe. Sign claims there's an attendant on duty, but lo and behold--no attendant in sight.
Skip this place. I drove less than 10min down the road to the Quick N Clean in McFarland and got a better wash in a more hi-tech facility for the same price with no issues paying for it.
