Initially, I was doubtful: in fact, we must first clean the shower with a classic product and then only apply the product Vileda. In short, it took me more time than usual. Too bad this is not a two in one: cleaning and prevention of dirt! But I waited a little to see, and I admit I am blown away: the shower is still impeccable one week after! The tiled walls shine! The water repellent effect, whereby water, limescale and soap scum are not deposited on the walls, really long lasting. And so, indeed, it is not necessary to clean as often. It's very convenient. I recommend.
