Quick Car Related Question

I did a spring cleaning of the car a couple weeks ago, which included cleaning the inside of the windshield, or at least attempting to. My first attempt with Windex left a lot of streaking/smearing. Second attempt on the driver's side with a isopropyl alcohol / water solution was more sucessful, but not ideal.

Does anyone have any favourite products for cleaning the inside of windshields, or should I just stick to multiple uses of the isopropyl alcohol and careful drying with paper towels to get rid of the smear/streaks?
