Windshield marks

Ok, hear me out. I have done the searching of forums and can't find anyone with a similar issue. I have noticed these vertical wavy lines in my windshield that are only visible when the windshield is wet. Once it dries, they are invisible. They go across the entire windshield from top to bottom, not just where the wipers wipe. They do not coincide with wiper pattern. They are not perceptible to touch.

Today I tried to get rid of them by doing using the following methods:
Invisible glass
Isopropyl alcohol
Meguiar's Clay bar kit
Razor blade
More invisible glass

The glass is now remarkably clean and clear when dry. But when wet, it's like I have done nothing. They have not improved one bit. Wipers don't matter. The wavy lines are visible for a few seconds even after wiping manually with a microfiber cloth. It makes driving in rain very difficult....especially at night.

Is something intrinsically wrong with the glass? Or, am I missing something here?

I have included pictures of when windshield is wet and when it is dry. Pics are of driver side only, but the entire windshield looks like this.

(FYI: truck is 2017 TRD offroad, if that matters)

 

I’ve seen the same thing.
Never could get ride of them either.
But I didn’t really care or try too hard either.

I am interested to see what others have done.

 

Suggest to take it to an auto glass place. Demonstrate the problem.

There may be a flaw in the glass lamination.

Remember, windshields are made of several layers.

 

I’d try an abrasive product. Any random polish you have for paint is fine for glass. Like Meguiars Ultimate polish.

I think it’s a residue of some kind from manufacturing or something. I have it too.

 

I don't recall always having this problem though. Seems like within last year or so. Makes me think not from manufacturing.

Yeah I am leaning more towards a glass problem given the entire windshield is affected and I can not even dent the problem with cleaners and clay. Still open to other suggestions.

Thanks for the replies so far.

 

You might be right. But try a test spot in upper passenger corner with an abrasive.

 

Nailed it. I read some random post on another forum where someone suggested using goggle cleaner for scuba goggles. You use it on brand new goggles to remove manufacturer sealant and other stuff. Had some on hand and tried small patch. It worked! Thanks for the suggestions. I’m sure there are other more dedicated glass/auto abrasives out there, but this did the trick for me. So excited for it to rain now!

 

Glad it worked. Ha I still have the residue on my glass. Just been too lazy to get after it. And like you said, it only shows up in certain conditions.

For future lurkers… CRL Sparkle is a great glass cleaner for this type of stuff.

 

And what are the odds the guy with residue on his Toyota windshield also has scuba mask cleaner on hand. Some things were just meant to be.
