It would be worth a try, Cillie... Do a small section, no sense wasting your time on a whole window, if it's not going to work.. I'm a preventive housekeeper.....not a crazy lady!!! Ha!
Funny you should ask though, I was thinking a short while ago about trying that stove top cleaner on my shower doors. Probably wouldn't hurt to try as it doesn't scratch the glass..
