Wolfgang Concours Series WG-1000 Auto Bathe, 16 fl. oz. TUFF SUDS II is a foaming technology that works by suspending natural oils and what we've dubbed "super polymers" within the foam-allowing built-up dirt and grime to be effortlessly swiped away. It will not strip wax or any type of polymer surface protectants from your vehicle. With a perfect, neutral pH balance of seven, Wolfgang Auto Bathe is completely safe for your skin and the environment.
