My car is flagged as non-wash since they use a non-touchless car wash. The SA tried to get the detailer to hand wash, but I picked it up too late in the day and no one was there. The porter did hand wash it off and I dried it before I left.
They said that the DEF is clear until it dries and they didn't notice it until we walked up to my car. If it is urea, won't peeing on your car cause the paint to be ruined?
