I have the shampoo while ago ordered here by the very cold winter my Smart (Silver) to brush. In addition I have 1-2 caps dissolved in a bucket of water and then applied with a sponge and plenty of water, leave for a moment and then rinsed single axle. The result was almost "legendary". The strong winter dirt (salt, dirt ...) just went from so. The difference between polished and dirty places was like night and day. For mixing and washing, you should wear gloves definitely!
I'm very satisfied. With virtually no effort great result.
