I am noticing a foggy kinda yellow residue which seems to be turning my headlight assemblies a little dull, is there anyways to clean them inside and out?? Thx

 

i dont think anyone has successfully cleaned the inside. for the outside, i use meguires plastic cleaner and polish. i know advance auto carries it.

 

I just cleaned my wife's yesterday with Blue Magic plastic cleaner and a buffing wheel that attaches to a cordless drill, worked great, now if there was only a way to stop the rocks from nicking them, that would be better.

 

i knows it sound crazy but i used some mothers polish on my head lights left them looking new its been 2 months no ill effects.

 

this might sound crazier than pfactor's method. i used brake fluid on my old headlights. just rub it on with a clean cloth about 2-3 times. then polish it with a soft terry after each coat.
