There was also a short thread (no pun intended) last year about the affect
of window cleaner with ammonia on plastic windows. I learned the hard way
after cleaning the windows on my brand new top a few times and noticing
"water spots" that wouldn't come off. The thread was on how the ammonia
reacts with the vinyl/plastic and clouds it. One individual even commented
on how cleaner with ammonia is banned from their computer lab after the
monitors clouded up. I'm not a chemist, but based on what happened to my
crystal clear new windows I won't use those cleaners anymore.
