Having read the reviews I decided to try a bottle. I am very pleased with it indeed. I think the trick is to do as the bottle says and not clean the window when the sun is shining. I used 2 cloths. One to spread it over the pane and the other to buff it off. As I have many windows I just used it on a few door and windows to try it out and went back in the sunshine to see if the product had smeared. No it hadn't. Great!
