The McLaren Car Care Pre Wash is a highly concentrated alkaline shampoo that dissolves
dirt and grime from the vehicle in a contactless manner. This product is designed to allow
the user to safely perform any car wash or detailing process by reducing the risk of swirls
and scratches that can be created by mechanical movements when using a wash mitt on a
heavily soiled surface. The Pre Wash is formulated to be used prior to shampoo
application, a crucial first step in any detailing process.
