I was skeptical and for nearly a month that I try, I admit I am quite charmed! I have not yet tested it on my wall tiles (level bath, the experiment would be to try) but the mirrors of my bathroom and all the taps. Usually the result was convincing. The traces on the taps were minimal and mirrors it was a dream! By cons, it is stated that it is for use once a week. Indeed, beyond the spots begin to settle and the water no longer slide.
In short, very good product to add to your weekly cleaner!
