Has anyone seen something like this? I don't think it's on the outside or inside. I've tried to clean both sides to no avail, could it be between the layers in the soundscreen windshield? It's a 2017 f150, it's wasn't there when I bought it in April.

 

I'm not sure what's causing that. I used to have streaky windows. My wife bought this Norwex microfiber glass cloth. Thing works great Eli,inatimg streaks, ormal streaks I should say. Ecloth makes a similar, cheaper product.

 

I had a streak at the top of the windshield and figured it out that it was on the inside. Regular window cleaner wouldn't remove it. I used this and it worked.

I had a very similar streak on my 2017. Didn't notice it when I picked the truck up but when I got home, I did.
I tried to get it off but it seemed to be between the layers of glass.
Dealer couldn't get it off either so they just replaced the windshield.

 

I hope that's not the case with mine. My first oil change is coming up soon, so I'll get them to check it out. I haven't tried to buff it out yet so I may try that.
