White spots in plastic/rubber trim

[MotorsportsAustin]

Anyone else dealt with these white spots in some, but not all, of the plastic/rubber trim on your Gen3? These show up especially bright after a wash, but are present all the time.
I plan to bring it in under warranty, but anyone know why / what these spots are all about?

btw, I doubt it's our city supplied water, my 2023 Bronco and all my other pre-2020 F150's haven't had this.

I don’t have them on mine. Your dealer will replace the cowl under warranty.
