How does a "waterless" eco-friendly wash work?

A waterless or eco-friendly car wash uses highly lubricated solutions to clean the entire vehicle. The safe chemicals encapsulate dirt and dust particles. This process is similar to how water removes dirt, but the chemical combination of a waterless car wash product is just as effective; you simply spray the surface of the car and then wipe it off with a microfiber cloth to avoid scratching. This process removes any light dirt or stains from the car’s surface.  A waterless car wash is only recommended for cars with light dirtiness that doesn't have excessive amounts of dirt, such as dried mud or other debris.
