Windshield Marks from Factory

I've noticed something interesting on my car. Whenever the windshield gets super foggy on the inside, all kinds of marks begin to appear on the windshield. There are circles that show up everywhere, and in the middle, what looks like a bunch of lettering saying "UV" and all kinds of other things. My guess is this is an imprint left behind from a paper that was once stuck on the windshield, and the circular marks were from the machines to hold the glass for the windshield factory install.
Has anyone ever seen anything like this on their car? I have cleaned the windshield thouroughly but they still show up if the window gets fogged up.

I am guessing it is from the equipment they use to calibrate and align the driver assistance sensors and/or the pre-sense camera...the latter of which is standard on all cars in the US.
The suction cups for installing the glass would be fitted to the outside of a window.

Yup. I’ve seen those on all my VAG cars too. They usually stick a paper on the windshield with car info and that leaves a mark on the windshield which show up when it fogs up. I guess the only way to remove it is to clean the inside and outside of the windshield vey well. You can check out detailing videos on YouTube that show how to properly clean the windshield/glass. One of my favorite detailers is Pan the organiser. He has a video where he shows how to clean windshields properly and even coat them.

Wow that's bad. I get frustrated with the off gassing from the plastic in the interior sticking to the windshield, but that's nothing compared to this mess.
I've seen windshields cleaned with magic erasers, but I can't bring myself to do it to my car. I'm afraid the thing will drip on my dash and cause discoloration.
