FYI - Beware of Solvents - Big Oops
So, silly me to think that I could get some sticker adhesive off the back of my stock windshield with some of that Goof Off stuff I've been using around the house. I've used Denatured alcohol before on plastics, but not this stuff. We're talking Xylene and Toluene here, petroleum distillates, and they distillated the heck out of my screen, leaving me with a hard, white, swirly fog where my sticker used to be. Looks like the stuff ate the surface of my screen and then vomited it back out from the rag I was using.
Needless to say, I am an idiot in need of a replacement stock screen (let me know if you can help). So, the lesson here is, don't be me. Stick with window cleaner and alcohol solvents for your windscreen!
