Purchasing wash packages online?? Guess what you can share the assigned code with friends or family to allow them to use your washes. When you arrive to the pay machine enter your code and then select your wash you wish to use. If you have a wash remaining on the package it will allow you in with no charge, if not it will show the price for the selected wash. Codes will be good for a year. Use it when you need it and once it runs out purchase more washes on the website or at the pay station.
