The car is only six months old and the stains were pretty bad. I had opted for the protection package when I got the car and they already had someone scheduled to come and take a look at it. I took the car for service at the dealer and they had no hope but tried and removed a lot of the staining. I cancelled the service call, and used the Zaino cleaner, rubbed it with my fingernails and it just came off. After that I used the conditioner and the seats were like new again. I already purchased a brush I can use to rub more effectively the leather for the next cleaning.
