This shit on my headlight is pissing me off lol. I'd try every chemical in the house to get rid of this and it's just not working. I even had to sacrifice a toothbrush to clean it. No luck.

I thought it was bird poop so I just tried washing it with water but it didn't work. The only thing that works is when I scratch it with my nails, but I don't want to go too far with that. Anyways here are pics and suggestions are welcome.
