Ok so I know this is a bad photo but I got kind of excited trying this out and just jumped into it! So I’m not sure where I heard this from but I gave it a shot and I’m so glad I did. I put a dab of toothpaste on a paper towel and just started applying it in the top of the headlight in circular motions. Then, I got a wet paper towel and started wiping the dried toothpaste off and that is how clean it looked. I didn’t do the bottom half because I wanted you to see the difference. If you do apply the toothpaste to the whole headlight you can just pour the water directly on the entire headlight and dry it. Isn’t this a great way to clean up your headlights?!
