I've got a can in my hand right now, and it says:
"Safe to use on most original equipmentmanufactured (OEM) and aftermarket tinted windows. Always test for compatibility when using on non-glass surfaces. Not recommended for for use on poly-carbonate plastic." I think if I were you, I'd call the tint manufacturer and ask, just to be safe.
It's just a window cleaner. Spray it on and wipe. Just works very well. Better than most soap & water cleaners. I have read a couple articles that say what really works good is to start with a regular cleaner first, then follow up with an application of Invisible Glass. Regular cleaner gets most stuff, and the Invisible Glass makes it streak free and invisible (so to speak).
