We've got great self-serve cash washes all over Waco. The place I go to you put $4 worth of quarters in and are able to use high pressure rinse, high pressure wash, high pressure wax, tire cleaner, foaming brush, and spot-free rinse for an entire hour. That's what I call getting your money's worth. Then I dry my car, Black Magic my tires, and shine up my stainless steel exhaust.
