I have this product 2 times put to use (full leather upholstery in the car). Since the first shipment probably was wrong and did not bring a scent of new leather in the car, sent me the seller to contact immediately a nice bottle 2. Smartwax. And now really spreads out a discreet leather smell in the car. The cleaning effect can be described as very good, you can see it on the white cotton cloths used to apply ;-)
