There are a lot of products on the market right now that promise to polish your vehicles headlights - restoring the bright driving lights you used to have. Most of these products promise a "like new" result for $50 or more.

But is there a cheaper way?

One bit of wisdom  that is currently going around is the fact that you can use common, ordinary toothpaste instead.  The theory is that toothpaste is a mild abrasive, designed to polish the plaque off your teeth - so that it could also polish the mini-scratches and haze that affect visibility.

Does it work?  I don't personally know, as I haven't tried it yet.  But this article I found online suggests that it does work - albeit for a short amount of time.  But to my way of thinking, even if the results only last short-term, toothpaste is much cheaper that the specialty products - and you already have it in your home already - so why not use it instead?
