Huge waste of money
I was so hoping this would be like the pink window cleaner I used to use, but was extremely disappointed.  I first tried it on my bathroom mirror, it wasn't too bad there, so I decided to try it on my car windows (interior).  That turned out to be a huge project.  Putting it on of course was easy enough, but taking it off wasn't.  After a lot of elbow grease, and an hour and a half later, I finally managed to get it all off, but the windows looked worse than they did before.  I ended up cleaning them again with my usual vinegar and alcohol spray.  I'm giving it one star only because that's the lowest option available.
