First time I buy shampoo for the car and I didn't want to invest a lot of money since I don't know how it will work. After searching on forums, etc., I got this one! It has a neutral scent, cleans and also has wax! I rinsed one panel at a time, then applied the soap with a microfiber cloth and rinsed with a gentle flow of water! You can immediately see the water running off.. I wiped with a leather cloth and it sparkled! I don't know what more those with 25 or 30 euros do, but this one does a good job!
