I've had this for a while and maybe those experienced can assist me with this dilemma.

I seem to have "spots" on my windshield and what seems like crystalized stuff. They look more apparent when humidity takes place.

Anyone know how to fix this outside buying a new windshield?

Thanks in advance

 

Try a little vinegar on the spots, see if that helps..You could also go over the windows with some clay, or polish..

 

Padron, I shall try the vinegar route. I've never heard of clay, nonethless, I shall search for this. many thanks

 

i have had the same type of markings....however once i turn on the defroster...they seem to go away.

 

It's pollution..when driving into the sun, it will resemble pitting.

Here's what I use:

Invisible Glass and a clay bar will remove it all...make sure the bar is new, as a bar previously used on the paint can transmit dirt and worse to the glass.

As y'all can see....this is my first post here. I'm a detail freak...and an ex Ford number dummy.

Thanks....

 

Both Mothers and Meguires sell a clay bar kit. The first time you use it...you'll be amazed at what comes off that shiny paint.

 

ExParts: I shall try that too! Thanks!

 

ahh I never used clay on glass, I never thought of that, but if it works then i'll be trying that in the spring on my 'winters cleanup' detail

 

I always clay glass. It's a standard part of any detail that I do. It's the last part to be clayed when I do it...

BTW, what you're probably seeing is the result of HARD WATER. The crystalization that you're seeing is most likely calcium carbonate (limestone) as a result of HARD WATER.

Clay should remove it if it's not etching into the glass. Additionally, the vinegar trick should probably do some for it...

Beyond that, try THIS.

Thanks RockPick. I shall try that this weekend!
