windshield rust

Weird question for my back window glass. It look like its rusty. I used a razor blade on one side to remove and check if was slash on or something. Its was not I check all the windshield and found more pitted rust in my glass. i will post pic this afternoon.

It sounds like someone did some welding and/or grinding on or near the truck. Those hot little pieces of steel will imbed themselves right into glass.

Yep, I agree with Captainfab.

Take some glass cleaner, wet down the glass, then with a sharp razor blade, swipe it back and forth across the glass.
You'll still have the pits where they embedded into the glass.

That's the best way to get rid of the steel particles without actually replacing the glass.
