You put in your quarters and get down to business. You are not getting out of this place for less than four bucks in quarters and that's if you work fast. I do the high powered spray first just once around, then the bubble brush once around then a rinse, then the wax, then you have to do the spot free rinse for at least a minutes. If you leave without a spot free rinse you're going to get spots everywhere this water is hard. I really like this place, I hide at it often. Sometimes I will drive through Wienerschnitzel, grab a dog and a drink and drive into this place - sit in the shade and eat (when there is no line which is most of the time), enjoy, check my email and get ready for some elbow grease. You can also vacuum your car afterward. Oh and yeah they have a few awesome change machines so it will break your $20 or $10 or $5 or you can swipe your ATM card LOL too dangerous for me this thing adds up.
