For lack of a better term, my driver side window is doing something similar to rusting. It has black speckly stuff on it, and I can't get it off. I've pressure washed it, I've rubbed it, i even took a knife and it won't scrape or scratch off. Do windows deteriate like this or is it just some really stubborn gunk?

 

Is it rail dust? Or perhaps someone was using an angle grinder near the truck? If the sparks from a grinder hit a window they can embed themselves into the glass.

 

Your grinder theory is possible. I hadn't thought of that. This is the best pic I can get. It varies in skze, this is one of the larger ones. It's all over the wing and main windows

 

Glass doesn't rust. If I'd have to guess 95fiveoh is right. That even looks like some kind of grinder schmoo.

 

Yeah I know glass doesn't rust, I just couldn't think of another way to describe what it looked like. That does sound like a plausible cause

 

Is there any way to get that out? Or am I just gonna have to get new glass? Or simply deal with it?

 

Sparks from an angle grinder can travel 15 to 20 feet. Any glass that is around a angle grinder should be protected. The particles embedded in your glass are actually rusting and that's why it looks that way. You might be able to get some out but you will still have the pits. You know what your two choices are unfortunately. . Sandy

 

I figured. Thank you sandy

 

Your best bet to remove them would probably be a clay bar.

 

What exactly is that and how would it be used?

 

Deleted double post

 

A clay bar resembles play dough and used to get railroad grime off new cars and years of contamination off of paint etc before polishing and waxing. Certainly acceptable for glass also as 95fiveoh mentioned. It may work for your issue but the pits will still be there. I would not rule clay bar out but I think you would have better removing power with 0000 steel wool in your case, but the pits will remain. I have used both on light window scratches with limited success. Sandy

 

I see. How noticeable would the pits be compared to the metal bits? I assume removing it wouldn't change the structural integrity of the glass since the glass itself is already pitted.

 

It would probably look like a small rock chip. Structural integrity should not be compromised. You could find the biggest one and use a pick to work around it for removal and see how it looks to you. Tough to say without seeing it. Just experiment at this point is about all you can do. Sandy

 

That probably answers all my questions. Thanks everyone for the replies

If I get it off I might post a pic just so it can be known what the end result is/the consequences of grinding near glass. It wasn't even me, it was the previous owner
