I just had my car washed and noticed all kinds of stains on the back seat. My car is 6 months old so I was surprised to see the stains still there after the car wash. I took a wet cloth and was able to remove all the stains easily from the leather seats. They also had not cleaned inside the cup holders. There were all kinds of shoe marks on the plastic behind the front seats that also came off easily with a wet cloth. All in all, I felt they did a very sloppy job.
