The clear headlight covers on my 02 accord have become cloudy, and I also noticed when it rained what appeared to be water/condensation inside. What is a good method of removing this discoloration/oxidation and also I assume the gaskets around the cover keep the water out. Is this a pretty big job ? This is really annoying to me, so I will fix them one way or another, if it's just time consuming no big deal, I think if I can get the covers off, and back on with good gaskets, and remove the oxidation I would be more than willing to invest the time into it.

Would appreciate any recommendations on what to use to remove the oxidation, and also about how to be sure to keep water out in the future.

Thanks, Clint
