Removing paint from polycarbonate

I got some overspray on my motorcycle windscreen. Is there any way I can remove it without effecting the clarity? Can PC be polished?

I know my A & P had a trick to remove overspray from my aircraft windshield, which was definitely acrylic/polycarbonate.

I'm really fuzzy on the technique, but I think is was some kind of paste made up with baking soda.

I don't think I'm clear enough on this to try this without testing it or some other confirmation.

I bet a headlight lens polishing compound would work.

The main concern I would have is that a lot, if not all PC windshields have some kind of coating on it and polishing it might remove the coating.

Novus plastic polish can be used to polish  PC. I've used it on several Helmet visors to get scratches out. As for the over spray you can try alcohol based hand sanitizer one of the paint guys iI know used it to clean plastic lenses that have a little over spray. May want to test it in a small spot not sure how it would work for clear PC.

It's in the inside of the shield not in the outside. I don't know if they coat the inside too and I'm not so sure the outside of this one is. It's a factory Yamaha shield.

I prefer Brillianize over novus for 1 step polish, but I don’t know if they do a 3(?) step kit like Novus does. Regardless, I doubt either will remove paint.

To the OP: Find a local shop who does museum display cases. They should be able to knock it out for you and not charge a godzillion dollars.

I'm a diy kinda guy. 

I'll work on it this weekend maybe. It's not a huge deal if I can't remove it. I just don't want to totally berkeley the screen up by trying something that will damage it. 

Non acetone nail polish remover or Dot 4 brake fluid should do the trick without fogging the plastic. Do a test spot in an inconspicuous area first to be sure.

In my hobby shop days, we used nail polish remover to repaint polycarbonate R/C car bodies (I don't think we got the sort of clarity you'd want for a windscreen, though we were also removing a paint job, not just some overspray). Brake fluid was the stuff of choice for removing factory paint jobs on model locomotives, though I believe those are polystyrene.

As a funny aside in the hobby/beauty overlap, Avon Skin-So-Soft debonds cyanoacrylate adhesives (super glue). Skin-so-soft or nitromethane...
