No, but it does get the dirt and grime off of it.

Car wash machines do make a lot of water and soap.  They usually use three or four car washes to get the outside of a car really clean.  But I think the soap and water mostly just run off and it’s the brushes and jets that clean the dirt off.  So there’s probably not a huge difference.
