At first I was very skeptical. Because of the many positive reviews I had initially ordered a cloth. It's hard to believe, but the advertising of the manufacturer agrees. So I had problems with cleaning the Ceranfeldes my e-cooker for ages. But I have very good cleaning agent used, but also an AEG-special products for cleaning and conservation of ceramic hobs. Such agents can be, if one uses the ALCLEAR Cloth, forgettable. This cloth has met all my expectations. It's hard to believe with a slightly damp (they say damp) cloth such results with simultaneous sealing (eg there is here after cleaning on the respective surface no finger marks) to achieve without any chemicals. If I had not even tried it, I would not believe it. What I have said here on ceramic hobs, applies equally to mirrors and window glass. At the car wash I have not yet used. But that will come. Of course, the cloth should not only wet, but also must be clean. It could also deposit dirt from previous cleanings. But then you also have to pay attention so with all other wipes. I can only express a buy rating with a clear conscience.
