on the information page that comes with the kit, it says that the Autodry Carwash system does not strip wax. The special soap contains something called dry rinse polymer, and that's the ingredient that allows auto drying process to take place. The only thing that bothers me is that it takes forever to rinse the soap off with filtered water mist, otherwise, it is all good.:thumbup: Cotsco sells it for a good price. $29Cdn with full sized soap.
