Tip for fixing Yellowing Headlights Options

[krom8]

I know that our Celica's headlight don't yellow but I've got a Corolla that did. I bought a cleaner kit made just for this problem which cost $10 but it didn't work . I ended up getting them clean with toothpaste. The plain white Crest tooth paste seems to work best. All you do is put some on a paper towel and buff the headlight with it then wipe it off with a clean towel or paper towel. They look like new headlights. Hope this helps someone else on here.

I cleaned both headlights, they both looked like the passenger side but now they are both clean. Wet sanded with 400 grit, then 600, then 800, then 1000, then 1500, then 2000, then medium cut buffingh compound, then rubbing compound, next polishing compound and finally buffed it with wax.


You could use 80 grit sandpaper or whatever if you wanted but you have to step up the grits to get the surface perfectly smooth. You probably want an 800 or grittier to start wirth though because your first rough sanding is what actually removes the old, oxidized plastic and then your just trying to make the surface smooth again. If you dont remove enough material at first then it wont look perfect when its done.
Oh and tape off the paint around the headlight because all these abrasives WILL f*ck your paint up if you oversand or buff.
Another tip, place a garden hose over the headlight with just a trickle coming out. it will clean as you sand and lubricate the sandpaper.
