I picked up a bottle (not the aerosol can) of Invisible Glass from Target along with some of the recommended Vroom microfiber towels.
This stuff is awesome. It cleans well, and has some volatile flammable content that evaporates in seconds, leaving a streak free windshield.
It is tint safe according the bottle, and I can vouch for that.
Not much to say. If you need something to clean your windows then get some. I think I paid $6 for a huge spray bottle.
