I don't believe there are any car washes in the entire USA that you can take a vehicle through safely. I think they all have the ability to cause damage and stipulations that they are not responsible for damages. In your case, depends what type of car wash you are asking about. Is the question about car washes with spray wand, brush less, the ones that have what appears to be rags rubbing all over the car, a car wash that has rollers and scratches the entire car or perhaps other kinds of car washes ? If there is an attendant there you can certainly ask them however a 19 year old high school dropout may not give you the answer you seek.
