If you're not familiar with clay bars for cars and which type is the best for you, chances are you probably go to a regular automatic car wash that is either a conveyor or roll-over style. In roll-over style car washes, the car needs to be driven on a wash bay and be stopped.

Traditional clay bar is exceptionally absorbent and it is very effective when trying to remove contaminants. A car wash can help get rid of the dirt on top of the surface.
