Puke Just What Are These EWindshields Made Of??

Bizarre. I had a bit of road tar on my windshield that I tried to remove with a mild solvent and all of the sudden it started to fog up. No problem, I figured, so I used some fine scratch remover to buff. It just got worse.
I thought it must be some sort of protective film that BMW applied. The only thing I could do was to try to remove it. I began gently (This is the key word) wiping it off and it seemed to be working. I figured as soon as it was completely removed, I'd just buff it out. All of the sudden the whole windshield started cracking and didn't stop until it fell to pieces. Now I need a new one. What's going on here. It's by far the biggest boner I've pulled so far on this bike.

What bike model and year, and what solvent?

That is far from normal.

I had a few choices of solvent to use. I already knew that lacquer thinner and acetone were out of the question so I used paint thinner. Plexiglass is not effected by it but this material must be something different. A little gentle rubbing and right before my eyes, it looked like someone shot it with a gun. Spider web cracks so deep the windshield broke apart in my hands! It was almost paranormal!
The good news is I just scored another windshield (For a song) from Ebay in excellent condition.
I'm almost afraid to look in my owners manual about cleaning it. It probably states something like "Never use anything but purified water and blow dry".

Paint thinner is never a good idea on plastics, though that does seem extreme.

I think I will try paint thinner on my spare and see what happens.

The manual does say to stick to mild soapy solutions, but that seems an extreme reaction. Just plain paint thinner?

I would guess polycarbonate. Especially after it's reaction to the solvent

My experience tells me it's an effect called "crazing", though yours is an extreme case. Solvents have this effect on acrylics and polycarbonates, especially after heat is applied to these materials. Windex can even do it. Undoubtably heat was used to form the windshield. It's the reason for the instruction to use soapy water only.

Bummer.

OK, in all fairness, it was mineral sprites, which is a mild solvent and I always assumed was paint thinner.
