Hey
The headlight lenses on my mom's 93 GS300 are yellowing and getting cloudy from age, and they look really awful.
Any tips on cleaning to remove the stuff?
Thanks

Use plastic polish or car polish. Anything harsher (like rubbing compound) may scratch the plastic.

Actually, I used rubbing compound then followed it up with the polish. They came out GREAT!!

buy 2000 grit sand paper and soak it in soapy water for 2 minutes. they wet your headlights with that water and sand each headlights for a good 5 minutes. itshould become grey and cloudy. next get rubbing compound and buff it all out. good as new.

Isnt that discoloring on the inside of the housing? you guys are talking about sanding and buffing the outside right? I have one housing that is yellowing, i thought it was on the inside. I tried a couple methods to clean the inside, that didnt work. maybe its on the outside.

the yellowing is due to sitting in the sun. It is indeed on the outside. My headlights use to be as yellow as big bird. but now is white as a dove.

Actually the plastic cleaners for pinball machines do a great job. There are three bottles for different coarsenesses.
