Back in the mid-1980s I was selling computers and one of my customers built commercial/industrial car washes and ran a chain of them in the area. I had a chance to tour his plant and some of the chemicals they were using were very corrosive, even when diluted. I don't remember the chemical names (other than sodium hydroxide, which is very "harsh", especially to aluminum). There's a good chance that the car wash industry has changed to different, less corrosive, chemicals since then but I still try to avoid them. YMMV
