Jet wash also depends how far the spray head. Too near can damage the paint, too far it does not remove all dirt because spray mist only...lolTypically the jet spray should be able to loosen most of the dirt and then they spray the soap “snow wash” which will further loosen any dirt stuck. If they are using better quality sponge, it shouldn’t be that bad too. I haven’t seen any car wash place rinse their sponge in between a wash but definitely the sponge used to clean the rims and car body has to be different.
There are centers that are good, there is even a detailing center that even dries your car with blower, no wiping. However Is expensive and need reservation....
