Soooo I was cleaning my intake valves and after letting the b12 soak I blew that wretched black gold out of there with compressed air. It splattered all over because i didnt seal well enough around the air nozzle well enough with my towel. It was a great time to say the least. I got it all cleaned up but it left little brown stains where it had gotten on my headlights.

Any ideas on how to remove? The b12 must have penetrated the plastic because i have wet sanded my headlights twice and the stains are still there. They arent as bad as when i started, but my OCD flairs up whenever i look at my headlights and see all the little specks.

Besides replacing the headlights any one have any good idears? I might try some 500 grit and see if i can get down deep enough to get the stains out.

i started at 300 grit and worked my way up to 2k to remove yellowing; maybe just need to start with something harsher?
 
The chemicals reacted with the plastic staring from the surface and it went inward. You will get it out if you keep wet sanding but it depends on how much was on it and for how long. b12 is some strong shit.
