Rceomended for any tinted filmed windows because of it's lack of ammonia i think. It works well too evaporates fast so steaks disappear
Mothers Glass Cleaner is also ammoinia-free, and safe for window tint. It's one of the best glass cleaners I've used -- easy, streak-free results. I usually use one damp cloth for "cleaning" and another cloth for drying using a light buffing action. Microfiber works okay with this, but I prefer plush cotton terry for my glass cleaning.
Forget about all the other products, the cheapest and BEST I just recently discovered. My wife works for Zales jewelers and for cleaning the glass cases they use Isopropyl Alcohol. You can get a 32oz bottle of it for about a buck at any store like Wal-Mart or something like that. Streak free shine everytime! I even use it on my chrome wheels. Give it a shot.
