You need to clean it. It's not easy to get it perfect. Check YouTube for some tips from pros.

Something I like to do is position a light in front of the windshield - it'll help you identify missed spots

I’d get some hanging desiccant packets (not the scented ones. That’s a lot of moisture.

DampRid fragrance free has worked for me (bought on Amazon)

Is that moisture on the inside? If so, that can't be good long term. I've never seen that on my Cab. Wondering if it's humidity. I live in a fairly humid environment. It's not Florida humid but it gets to 80% regularly.

Looks like condensation, does this occur in your other cars? Do you leave bottles of water in the car? Is it hot and humid where you live? Need more info.

It is about as humid as it can be where I live and that dos not occur in any of my cars...unless there is significant moisture (more like a leak) in the car. I had a Ford Flex that had developed a leak in the moonroof due to a clogged inner drain line and it would have condensate like that on the inside of the car when I would enter the vehicle particularly in warmer weather. You would never know there was a leak but when I took it in for service and commented to my advisor, they ended up finding water under the carpets. In my opinion (and if that is on the inside) I would have the car checked.

As for that oily film that can accumulate on the inside of the window, I follow this approach form YouTube university: put about a gallon of warm water in a buckeet and ten add about half a dime drop of dawn to it. Dip a microfiber rag and wipe the window thoroughly. Use a squeegee to remove water and wipe any remaining water with a very clean/dry microfiber cloth. Very effective.

No there’s no moisture inside. It was raining. The streaks are still there when dry as well

This is seriously the best glass cleaner I have ever used and I have literally tried them all. I had to import my first two bottles from Canada.

That looks like the off-gassing from the interior plastics and materials, which is nothing that a soapy, damp microfiber towel and a clean and dry microfiber towel can't fix.

The outgassing doesn't disappear quickly. I have noticed it takes a year for it to slow down.

Not sure how much or long you park outside in the sun, but I'd definitely get one of those windshield sun blocks. The outgassing eventually slows down but when parked in the sun you will always have it.

my car is usually parked in the garage unless i drive it to work and when i do park it outside i use the sun screen. interesting never had this issue with any other car. wonder if the windshield on the T is thinner? i've heard of issues with the GT3

Agree. I like the Invisible Glass product to deal with this annoying windshield film: https://a.co/d/fEeN3LB

Good stuff and it has been my go to for many years, but it does not hold a candle to Bilt Hamber Trace-Less.
