Glass cleaner, then plain water. GM requires that plain water be used to clean interior glass during new car PDI.
"Interior glass should be cleaned with plain, clean water to
eliminate any film or haze on the window and to help prevent
fogging, a major customer dissatisfier. Refer to Corporate
Bulletin Number 03-00-89-006D for more information. The
New Vehicle Pre-Delivery Inspection form also recommends
using plain water to clean interior glass"

No glass cleaner I've ever used (and believe me, I've tried A LOT of them), have ever left the inside of the windshield streak-free...I've even tried other non-traditional methods and they don't work either...I'm convinced that the gas given off by the dash baking in the sun is impervious to any glass cleaners once it gets on the windshield...
