I have a super glue stain on the front windshield of my car, what is the best way to remove it without scratching the windshield?
You'll need some acetone (or your girlfriend/wife's liquid nail polish remover). Apply liberally, and then you just have to work at it to get it off and that's the part that might be difficult if you're trying not to scratch the glass. I'd try with a fingernail I think, given that's the least likely to cause scratching. Link below gives specific instructions, follow the ones listed under tables, floors, counters etc.
