Anyone got any ideas how I could make my headlights clear again, if at all? They are pretty yellow!

Thanks!

I used a polishing compound that came in a yellow bottle with a buffing pad for a drill on my daughter's 93 Legacy. Made alot of difference in the brightness of her headlights. Do not use a rubbing compound as it would scratch the lense, the polishing compound is white and has no grit to it. Glenn Taylor.

Novus plastic polish system:

For a fogged or yellowed polycarbonate lense, start with #2, then finish with #1.

Dealers are getting about $100 for taking some Subaru brake fluid and using a clean cloth, polishing the lenses.
It works! Better than using the polishing compound!!

We used some aluminum polish on a '93 yellowed headlights. What a difference! Cheap too! Good Luck.

Could you by any chance explain the physics or chemistry of it?

Glad you like it. Cohen's songs are about the only ones (+ a couple of french singers maybe) I really listen to the words of.

I did not have good luck using polishing compound. What I did was to use a razor blade and with moderate pressure scrape the yellow plastic off the lens. You can see the shavings are yellow. When done I buffed the lens and saw noticable improvement.

If you do not want to pay for polishing compound, you can go to a discount store and buy some cheap toothpaste (the paste type, not the gel type) and apply with a soft cloth and elbow grease. Essentially the same stuff as the compound, and cheaper too! (This also leaves your headlights smelling minty fresh :grin:)

I read this thread today and tried it on my tired, '90 Legacy lights...It WORKED GREAT!!!!! File this under why the fuq did I just learn about this now? I cleaned the dirt off them first then rubbed brake fluid on them and dried them. It took maybe 5 min for both and they really look brand new I'm shocked.

So, this may be a stupid question, but did you all do the inside surface as well as the outside? I tried prying a clip off my headlight to get to the inside and the plastic clip just shattered. I stopped there. If it's not necessary I won't even try it.

stop there. By the way brake fluid can damage paint so be careful with it.

No, that's a great question...I only did the outside.
