I just don't get it

What about some diluted down ammonia?

Use google instead of opinion.

glass polishing - Пошук Google

There are a ton of products that will work. Just do whatever on a corner before doing the whole thing to make sure it will not damage the glass.

I use denatured alcohol. It removes anything solvent based. Then reclean with glass cleaner to remove remaining residue.

Denatured alcohol is my go to, if that fails then its on to polishing compound

OP’s windshield looks like hard-water stains to me. As others have already mentioned, vinegar is the solution! Hard-water left to dry in the sun will deposit calcium and other minerals, which are very difficult to buff off. Vinegar is acidic and dissolves the minerals very easily. Just mix vinegar/water 70/30%. Use a towel soaked with this solution and let it rest/soak on the glass for about 10-15 minutes. Then wipe off with more solution. You’ll be amazed. Once you get it crystal clear, I would suggest applying a coat of wax initially to prevent water stains from happening again. Usually, if you use a good quality car wash soap, like Meguiers, or go to quality automated car washes that apply wax coatings during the final rinse process, your windshield will eventually build a protective coating over time.

Haven't tried alcohol yet. I'll be trying it tomorrow after work. I feel like the glass needs to be "stripped"

If you drink enough of it you won't see it.

I did try vinegar mix but I didn't let it sit like you said. I'll try that today. My next step would be triple ought steel wool or polishing compound

I definitely would not use steel wool. There are glass polishes and hard water deposit removers that would work far better and with less damage. You might also ask a detail shop.

Vinger didn't work on my windshield. I don't have before pics unfortunately but it had nasty water spots and lines from the wipers. They were only visible in low lighting. But nasty.

I used windshield polish from amazon. It's similar to buffing compound. Elbo Grease + a soft cloth and a 6" windshield buff pad attached to my cordless drill does the rest. It left no marks and the glass is like new.

Fine glass polish

I followed it with a coat of wax for protection. But they sell stuff designed for windshields.
