I have tried a dozen different window spot removers and they all failed to do anything. Last month, I read on this board, a member used "Whink Rust Remover" on his water spots on his windows, I tried it and the windows are perfectly clear! That stuff is great! You got to be careful, but it does work. I have really bad spots that I tried razor blades on, but nothing worked.

Whink works wonders!!!!!
