Loving my new-to-me 2018 GTS except one thing - the windershield has what looks to be a chemical-like (washer fluid?) haze on it. It appears that the car spent most of it's time in New Jersey, which would be a state that gets cold in winter etc...
I've tried Griots glass polish and ultra fine steel wool to no effect.
One idea was that it had a protective film that could be peeled off but I just don't see that any such film is there.

Griots has glass polishing pads that should be used with the polish on a rotary polisher. You won't get that far by hand, assuming the residue is something that can be polished off.
I had good results removing residue with those pads, a rotary polisher and CarPro glass polish but any cerium oxide based polish, including the Griots product, will work. It just takes a lot of effort.
I bought one of these heavily advertised rectangular cleaning pads on a pole. They are made so cheaply that you have to treat them as perishable, but what a great job they do inside the windshield. Because of the steep angle, it is tough to get in there with just paper towels. It was about thirty bucks, which is at least three times what it should cost, but very effective with just Windex. It took months to arrive as it is a direct China product. Maybe just Google this, as I can't provide more information.

We just got something that sounds similar, but it’s just a sponge with a chamois type material covering it. Haven’t used it yet, so no idea if it’s effective, but it was around $10 on Amazon I think.
I have a brand new 2023 Macan S. Had problems with the windshield fluid put in by the delivering dealer/factory. seemed too concentrated and left a stick residue. Solution was to drain and dilute it. Porsche NA is very specific now to not use rainX or anything that is not water based in the fluid reservoirs.

I had the same issue, it was pretty bad on a black car. I captured a lot of it by placing bottles over the nozzles and running the pump. I then diluted it with distilled water. The rest was drained by running the pump when it was raining out.
I made sure before my service visit to fill up the tank with my diluted version so they don't refill it during the routine check/fill fluids step.
Did you get the residue off? I don't have this problem in the Macan, but have had it on other cars and tried alcohol, vinegar, 0000 steel wool, clay, it wouldn't come off. Didn't go to a polisher...
I had this problem after hiring an actual clown to ceramic a car. I didn’t know he was a clown until after he did the work. Almost everything that could go wrong did including windshield chemical haze. It disappeared after about two years meaning it lasted longer than where the ceramic actually belonged.
I've got a solution for you: Come to Colorado, go for a road trip, and rock damage is nearly guaranteed! My Macan had a windshield chip so bad we had to find clear packing tape and tape over it. Rain was coming in and dripping onto the dashboard. Of course it was day one of a seven-day trip to Utah. Oh, make sure your auto insurance covers windshield replacement first!

Windshield Chemical haze?
