Can you use a clay bar on the windscreen to remove contaminants. I seem to find that my wipers only work smoothly after really cleaning the screen hard and then not for long.
You can see that there are areas that are not clean as the cleaner is evaporating no matter how hard you rub. Even though it looks spotless afterwards you know that it won't last long. :bang:
