Despite "Nano" I bought the part, as the screens in the car there is a Greul.
I have normal window cleaner tried, these wet wipes which one (streak-free of course) must rub with a special dry cloth and other resources and tips.
Looked at first quite good, hardly came the night and then maybe to rain and you could see the misery. Strips which are not really made better the view, but rather worse.
After the winter and the many warm air blower, especially on the windshield, I was once again at a loss before the shelf with all the wonders parts and then have it accessible again.
Skeptical applied and waited for the night.
Vorneweg what to use. Spray on the disc, distribute with a soft cloth and then wipe with a lint-free cloth other.
I saw the other remedies, on the towels which I jerked. That was never the problem, but the large-scale removal of the coating on the inner pane.
The night, bwz. the dark morning came and I was surprised! The whole looked really good. Later, when times even joined them rain I was thrilled. Rarely had such a clear, streak-free glass.
Respect!
Now something else to life. I am here not stop too long. I am of course purely to the large area, and then in the corners. Putz direction was not only one, but there came times horizontally and vertically times.
Estimated 3-4 minutes for the windscreen wiped with the resources and perhaps 2 minutes. So really manageable time.
The part advertises yes (Nano nano) so that the clean effect long / longer lasting effect. Since I was also excited.
I've seen every now and then when the sun came through so obliquely as evidenced by strips, also at night.
I have not noticed anything, and only after 8 weeks I have again the Scheibenklar used. Frankly even more because it was the interior again necessary, and if already it right. Needed it did not have the disc.
Conclusion: Finally a disc cleaner which not only promises but also delivers what it says. Quick and easy application and long Vorhalteeffekt.
Of this I'd like to means!
