First of all check for the yellow haze on the headlights by scratching it. Now take toothpaste and then apply some of it on to the headlight. Now you need a dry towel to clean the headlight. Start by rubbing the toothpaste over the headlight with this towel. You have to rub it hard so that the toothpaste cleans out the yellow haze. Start from the middle and make circular motions with the towel. Then start to spread out towards the corners of the headlight. Keep on doing it and you may even feel tired of it. After sometime you have to check again for the yellow haze. It should have been wiped off. That‚Äôs it.
