I wouldnt take mine to one, but then again I know my car wouldnt clear the roller that tugs your car along.

And the problem with car washes is this, they recycle their water, and those brushes have seen god knows what, if a car before you came in covered with mud, those brushes are going to beat the mud right into the clearcoat.. and yes, they will scratch clear coat, a pair of denim jeans will scratch a car if you rub up against it.

the force those brushes hit your car at is like beating someone with a wet noodle.

im a detailer and I hand wash everything, **** a carwash
