I have a hard time believing its the windshield but I may be wrong. I clayed the windshield the week before the new wipers were installed as part of my big detailing, and I have been weekly using the same glass cleaner (Mequiars Professional) for over a year with no ill effects. The washer fluid in the reservoir is whatever was put their by BMW service. The issue seems to be squarely associated with the new wipers.

If anything is "dried out" I would believe it would be the rubber wipers, not the glass.
If your sport doesn't put blood, dirt or grease under your fingernails,
then it's just a game.
