I still just use some toothpaste, a wet cloth, and some elbow grease everysix months or so. It cleans them up, plus gives the vehicle a nice minty fresh scent. When we bought my wife's Dodge minivan (used), I thought I'd have to buy new headlight lenses they were so cloudy. But toothpaste cleaned them up very nicely. It's cheap too.
