Excellent cleaner for car windows, cleans thoroughly and leaves the surface ready for the application of a water-repellent product.

I found it quite good and interesting. It really does what it promises. Of course, it wasn't particularly easy to remove during rinsing, but that's okay. Surely you can achieve the same result without this particular product, but the windows were indeed much cleaner. And it was more noticeable at night since I don't use any window products at all, so there wasn't the slightest haze.
