I got mud in my lights, aftermarket black headlights , a while back and cleaned them all out with water. But now I've got a couple water spots and still not as clean as they should be.

Has anyone ever poured Windex or ammonia into the light to clean it? Or know of another good way to clean the inside without splitting em open?

 

I would think something that evaporates quickly would be good long as it doesn't harm the palstic.

 

That's why I was thinking windex or ammonia, maybe alcohol??

Anyone know if those are plastic safe?

I might test it out on one of my old lights.

 

I've got fine dust in mine...and it drives me insane!!! Something like CRC Mass Airflow Cleaner evaporates really fast and is safe for plastic. I havn't used it onthe headlight housings before, but have used it on my MAF. I'm going to cure mine by taking the housings apart...for some oven action.

 

What about just some compressed air?? would that f' up the bulb?

 

Yeah, little stuff like that drives me crazy too. I'll think about it all the time, like OCD or something. lol

I might test that stuff out.

I thought about that. But thought it might get oil/water in there as well.

 

wax and grease remover dries up quickly, maybe try that?

 

I agree its very annoying, I have my tail lights full of sand from the dunes and I have no clue how it gets in, let alone how to get it out.
