Windex contains ammonia.
You should not use it with tint, even factory tint.
I learn the hard way on our new Toyota bought last year. Basically I used Windex on the factory tinted windows once every 2 weeks when I wash my car. For about half a year, through repeated use, there were tiny specs of white bubbles. Very tiny and hard to see, but it is there.
The stoner invisible glass is the way to go. That is all we used for my wife's Forester. So far so good.
