How do I do it? Headlight restoration
My headlights are getting hazy again. I bought some restoration stuff a while ago and it worked…good. It’s that time again but I misplaced it and don’t feel like going out to get more. Anywho, what are some actual DIY headlight restoration solutions yall have tried and actually work for a while? I tried baking soda and vinegar paste, smeared it on there and really tried to scrub it in. The rag was yellow when I lifted so I guess it’s doing something. There’s still some spots left and I was thinking of doing sandpaper. I don’t want to mess it up so what sandpaper should I start with and move up to? Also, should it wet or dry? I know this is a lot; but I really appreciate any suggestions!

There's only one way to permanently restore a lens. The kits, polishing, and ceramic coating/sealing/etc are not really long term fixes as you have found out. And the other gimmicks, like wiping with brake fluid, toothpaste, baking soda and vinegar, etc, have no chance of lasting at all.
I have restored lenses on at least 70 vehicles in the last 15 years. The link below is my reply to a post regarding headlight restoration from a year or so ago. It's not a difficult process, but it does take time.
