Getting the cloudiness off the inside of the windshield

[RadzShadow]

I didn't do any of the suggested above. I had the entire car ceramic coated on the exterior.
I had all the stock tint removed and replaced with Xpel brand.
I had the windsheild coated with Xpel clear UV tint.
All of that work, with lifetime ceramic maintainance was US$2300.
I clean my entire car with a spray bottle of filtered water and a few microfiber cloth towels.
The dirt rolls off and I have no wipe marks that are left over.
When you invest this much into a car, invest a bit more to protect it for the long run.

I did use this to clean everything after ... and still use on different parts with the microfiber clothes: https://www.amazon.com/dp/B0DPXSH4FN?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1

I don't believe it has anything to do with wiping the windscreen inside...

More that there is no airflow in the car when the windows are up, no fan on, no external air coming in or at least room temp... It's now finishing up Winter in Australia so by breathing inside the Z, the air heats up and fogs the window whilst it's much colder outside... then having to turn the AC on and the window clears up... that's what I've noticed in my Z.
