Where the dirt actually hides
The sides and hood are the part everyone sees, but the hard grime sits lower. Brake dust bakes onto the wheels and the tires, and the underside of a car holds on to whatever the road threw at it: winter rain, mud off farm roads and the dust that blows through the Central Valley all summer.
That underneath grime is out of sight, so it gets ignored. It is also the part of a car that sits wet and dirty the longest. The Deluxe Wash is the package for the lower half of the car, with a layer of wax over the paint on top.
