I was a bit critical because of the large quantity that is offered, but that result has me positve überrascht.Der cleaner does a great job, dirt particles are washed away, that takes a little longer- evaporate, then creates a protective film, I can not say how long this holding, but what holds already ewig.Ich am very satisfied with the product, especially as a good price, performance ratio is available here. Caution: Either use outdoors or with the window open !!! This is also on the can.
