Personally I would not. I've always been concerned about the long term effects it might have on the diamond shield or 3M protective film under all that glass. Every window tint installer I've talked to recommended not using Windex on the film...I know it's not the same stuff, but both are some form of plastic. So I don't take any chances.
I use Gel-Glow, a heavy duty RV wash and wax fortified with carnuba wax with streak free success and no apparent damage to the 3M. A cap full of it per gallon of water, along with my trusty soft scrubber/squeegee does the trick.
What I want to know is, how come that windshield got bigger every time I cleaned it??
