The headlights on my car have been foggy for a while– there’s a natural build-up of grime that eventually makes the plastic look dull, with a corresponding decrease in brightness of the lights. When I talked to the local Honda shop, they said it would cost $80 to clean them.
So I poked around the internet a bit and found many people who recommended a home remedy: buy a tube of toothpaste and rub the toothpaste onto the headlights. There’s a slight abrasive in toothpaste, and it can remove the grime. Hey, better than $80, right? I bought a tube of high-quality toothpaste for 98 cents.
Then I spent about ten minutes rubbing it onto the headlights and cleaning it off. The result? No change at all. Sigh. I guess home remedies aren’t always home remedies.
