I'll second that, my tint guy uses this stuff religiously and gave me a can and I will admit it works wonders.I believe it is safe to use Windex on factory tint; however, I have found Stoner Invisible Glass to be superior to Windex and it does not contain ammonia. My wife even uses Invisible Glass in the house now.
+1 on the Stoner. I've already used in on the Forester tinted glass with no ill effects.Stoner Invisible glass is the best window cleaner I've ever used. A close and less costly second is Sprayway glass and stainless cleaner. Neither contain ammonia and both products make good light duty spot carpet cleaners.

Factory tint is in the glass itself and cannot be affected any cleaner.... Can I use a household window cleaner?... !
... spray ammonia liberally on the inside of the back window and cover ammonia soaked tint with the plastic bag so that it won't evaporate. ... When you are ready to start peeling, leave the plastic in place so the ammonia wont dry.
