After reading the rave reviews for this product from others here at Revain, I ordered a bottle of Zymol Z507 Leather Cleaner and got to work. worn skin of my car with beige leather interior. I had great results. With a white microfiber cloth and a little rubbing, years of dirt and grime appeared in minutes. With each subsequent use, that white towel got dirtier and dirtier, and the upholstery on the seats became fresh, clean, and renewed. After the third round I was ready. The skin looked like new again, was smooth, supple and last but not least smelled great. It is noteworthy that it does not darken the skin like some well-known brands do. Also very soft. no harsh chemicals. This is a great product that delivers great results with minimal effort. It's head and shoulders above other skin cleansers -- cleansers that require large amounts of "elbow lube" to produce lesser results. I highly recommend it.
