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 think 400 grid paper is to raw for headlights... 800 is the lowest grid I'd use, followed by 1000, 1500, 2000 and then, if acquirable, finish with 3000 grid. Do each sanding in straight moves, no circular sanding, and each grid paper in cross work (800 horizontal, 1000 vertical, 1500 horizontal...).
Keep the surface wet when sanding, water in a sprayer comes most useful.

For polishing until clear you need a paste for polishing plastic (some even say headlights), and you just polish it off until clear... Some even do this with tooth paste, but I've never tried that.
