The inside of my light covers are badly Oxidized,I tried turtle wax,cant find the sandpaper I need,and the inside has water. Any fluid/chemical/technique I can try to clean these things up with? The bulbs come out of the covers through the back.

I have had good luck useing Windex glass cleaner to get all the moisture out. The headlight houseing does have to come off the car and then rinse it out with the windex. Windex will sweep out the water and dry like a charm.

The dullnes can sometimes be sanded with 2000 paper and buffed with a machine . Mequiers plastic cleaner #16 can also can help clear some of them up.

There are instances where a aftermarket replacements weather better the stock. . .

My Dad's chevy truck has the same problem. The plastic gets "cataracts"; it's dull and slightly yellow. I polished the outside surface with some machine glaze. It worked really well. I expect a normal rubbing compound or polishing compound would also work well. As for the inside, I don't know. That would be pretty slow and tedious to polish by hand if you're trying to work through the light bulb hole.
