Tunnel Wash uses a conveyor that keeps cars moving even if there are a few cars in line. The entire wash cycle lasts no longer than four minutes and since there is no waiting for the car in front of you to finish, you will rarely spend more than five minutes from the time you pull in, to when you are out of the carwash. We can wash up to 200 cars per hour! Therefore we are the most efficient way to wash your vehicle.
