A buddy got a new windshield for his vintage ride and has tried endlessly to get whatever it is off. It almost appears as a fine overspray of paint; no way this coulda happened as windshield was put in after painting. Tried all sorts of cleaners, razor blades, even lacquer thinner. No luck. Thought I had read a post while back on something like this; but couldn't find it. Anyone run into something like this? Thanks!
 
use denatured alcohol if that doesnt do it I dont know what will.
 
0000 steel wool and rubbing alcohol might fix it.
 
He sure the plastic between the layers of glass isn't going? Try some glass stove top cleaner in a corner... with your fingers!
 
Any pics of the problem?
I've always used 0000 steel wool and foaming glass cleaner to polish all glass. I'll then apply wax to the side and rear glass.
If the steel wool polish doesn't remove it, I'd say you're fooked.
Pictures though please!
 
Hey all thanks for your tips! I'll see about getting photos...hmmm gotta wonder as well if the fooking glass is defective...
 
Pictures & any ideas of what it "possibly" could be and I can help you with what will dissolve it off. However....since you say you already tried a razor blade, it makes me think the "delamination idea" might be correct. Let's see those pictures please!
 
What "Brand" is the glass ? When and Where was it made ?
 
Is it an actual liquid/chemical film you can feel with your fingers or is the surface dry to the touch?

Was it like that when he received it? Or, did it do that after it was installed?

Reason I ask is, I did some interior work on one of my cars and I used the spray on glue to adhere material to a few surfaces. Right after that my glass on the interior started hazing, predominately the windshield.

Only thing I could attribute it to was the chemicals in the spray adhesive, it took lots of effort to get it off and keep it off. It seems better now.

If he did something similar, maybe that's why.
 
As others correctly stated, possible delamination. Windshields are a sandwich of inner & outer layers of glass with plastic sheet in the middle.
 
Thanks again to all! I met my buddy this morning for our routine coffee BS session and gave him a copy of all your replies. His car is in storage so photos are a little complex to obtain at least right off as the haze shows up in sunlight. He mentioned there are a couple of finger prints too. I said take a couple pics with the flash on to see if anything might show up. If that works will post.
 
My friends father that owned a body shop back in the day used 0000 steel wool and rubbing alcohol on the glass. He then warmed water and put it in a spray bottle. Mist the glass with warm water and scrub with newspaper. Followed up with glass wax and finished.
I watched him do many cars using this method.
I did the same technique on my duster back in the day and had great results.
Going to try it on my road runner soon.
 
Going to sound funny but tooth paste will take it off. Just do a little spot then see what you think.
