Have you noticed how yellow and grimey your headlights have gotten?
The solution is very inexpensive.
I've been selling headlights on e-Bay for awhile and have found that even the yellowest of headlights come clean with this simple proceedure.
First go to your local discount store and get the least expensive whitening toothpaste. These toothpastes have a tendancy to be abrasive and will remove even the nastiest road filth.
Next get a soft DRY cloth and apply a generous amount to the glass or plastic.
Gently rub it on, let the paste do its work, then rub it off . If it is stubborn you can finish up with a damp cloth and mild spray cleaner.
That's it! Dry and you are done.
It kind of works like polishing compound.
You'll improve the looks of your car and you could improve night driving as well.
One tube of toothpaste can clean about 8 to 10 headlights.
