As the leather seats of my Porsche (944) are over the years become quite dirty, I decided to buy the product. The seats were then significantly cleaner. What new did not see the seats, unfortunately, but I'm assuming that my leather this is already too old.
On one other vehicle which by 2010, I also tested as the product and see; the seats were really like NEW!
The product is perfectly acceptable for the money. The content is sufficient for 2 car interiors.
