I have to return to Mister Car Wash to leave a better review but they were decent. There aren't too many other car washes like this in Madison. I went on a Tuesday morning so my car was the only one there and it took about an hour (I had a foul smell in the car..long story). But the staff at Mister Car Wash was very friendly and they all put in a big effort to get the odor out!
I plan on returning.
