When a car is new, its chrome and glass surfaces appear bright and shiny. Over time, scratches, rust and other buildup can cause these same surfaces to become dull. When the headlights of a car begin to age, the surface will begin to oxidize, leaving a hazy white or yellow film. Not only is this dull finish unattractive, it can also impair the release of light onto the roadway, compromising safety. Fortunately, cleaning discolored headlights is a quick do it yourself project.
Wash the Headlights
Before attempting to remove oxidation, it is important to wash the headlights with your usual car wash, water and a sponge. This will remove surface dirt from the lights, leaving a clean surface for removing the discoloration and haze. After washing the headlights, be sure to rinse and dry them thoroughly before moving onto the next step.
Polish the Headlights
Dip a microfiber cloth into a polishing compound made specifically for automobile surfaces. Rub the compound into the headlights in a circular motion. This will help to break up the oxidized particles, leaving the headlights clear and shiny. Rotate the cloth, as dirt builds up onto that section and apply more compound to the cloth. Take your time during the polishing phase, as it is important that the compound begin to dry on the cloth. As it does, the particles will become more abrasive and better able to remove the haze and discoloration.
Sand the Headlights and Finish
Place a piece of 1000-weight sandpaper in water for 15 minutes. Rub it into the headlights in a circular motion. This will remove any fine scratches that can cause a hazy or discolored appearance when dirt becomes lodged into them. Do not use any heavier weight of sandpaper, as it could cause scratches rather than removing them. When you are finished, polish the lights with the compound one last time. Wash the lights with the car wash soap to remove grit. Rinse and dry the headlights with a lint-free towel.
