1.) Go out to your local Autozone or auto parts store and buy : Eagle One aluminum and rim polish. It's in a small silver can and it is a white polish.
2.) Go home and take out your headlight. (This process can be skipped if you have steady hands and trust that the paste will not get onto your car's paint) Do one headlight at a time.
3.) Take the can and unscrew it.
4.) Make the rag go over two fingers and wrap around like you would when you polish shoes.
5.) Take up some of the polish and apply liberally onto the clear outside part of headlight. You will see the towel/rag get a little black but it is o.k. DO NOT LET THE PASTE DRY.
7.) Wipe the paste all off with the same rag.
8.) Wipe the residue with a paper towel or another clean towel/rag.
9.) Wax over to add protection so it won't happen for a while.
10.) Put back on the light.
11.) Stand back and fall in love again with the S14 lights.
This process can be done with any plastic lights that are crusted over including but not limited to... BMW plastic headlights, Maxima plastic headlights, and even Z24 headlights. I even used this process for the rear lights and they came out great.
Unfortunately I do not have before and after pics because I didn't have my digital camera yet but try it out and see what it can do for you. :pface
