seems to depend on just what they used Grigg -
"Does Armor All® Car Wash Concentrate contain wax, silicone, ammonia or petroleum distillates?
Armor All® Car Wash Concentrate does not contain any of these ingredients."

I'd find out exactly which product they used and give ArmorAll a call and ask - if it's gonna be a problem, the car wash guy should foot the bill
