I work part time at a Toyota dealer just outside of Chicago. Two days ago a guy bought a new Toyota Rav 4.He requisted that it not be washed or cleaned up in any way. All he wanted done is the stickers taken off the glass. The guys that prep new cars never seen this before. Since these guys were very busey they were very happy that they had one less car to do. We are careful when we clean new cars. Most car just get washed, a few will get spray waxed. We use Technitions Choice Spray and Glow which is a very good spray wax.
