Wet the headlights with water
Add a fair amount of toothpaste across the headlights
Rub the toothpaste all around with the damp cloth
Rinse with water and dry it off with paper towels or a clean cloth, preferably microfiber.
Voila! You save $20-$40!
Good as new! Sorry, not the same car but the pics were too dark.
Any toothpaste will do, though, it would be best to get any whitening and teeth polishing toothpaste.
