Don't use soaps or dishwashing liquid, you will have water spots from the water-soap solution when it evaporates off your windshield, and you risk stripping the wax off your paint.
Sir imho, water spots cannot be caused by filtered/distilled water. If there would be blame it to the elements present in the environment, but at least this soap solution will gently wipe of sticky substance like carbon and oil combined from the air pollutants - just to name a few.

I also disagree of the washer stripping off the wax in the paint as it should be directly aimed at the windshield, unless otherwise you install performance washer that can blast water into your whole car, afaik.

Hth.
