How to Clean Your Car Headlights – 13 Steps

The headlights of your car are vital for your vision most especially when the roads are dark.  As headlights are exposed, they catch dirt and pollutants blocking the plastic lenses and thus, scattering the light meant to be directly, lighting your way.

What You Need

  • liquid detergent
  • Car wash cloth
  • Several rags (with microfiber detail)
  • Painter’s tape
  • Rubber spatula
  • Razor
  • Household sponge (large and thick)
  • 5 pcs. of 8” strips,  500-grit sandpaper
  • 5 pcs. of 8” strips, 1000-grit and 2000-grit sandpaper
  • Pitcher, gallon size
  • Spray bottle
  • Headlight lens or plastic polish
  • Alcohol
  • Headlight lens sealer



  1. Start off with the first headlight you’ve chosen. Wash the lens thoroughly with liquid detergent.  Then rinse it and let it dry totally.


  1. Put painter’s tape to the car’s body that surrounds the headlight, most especially the rubber seal surrounding your headlight. Using the rubber spatula, flatten the tape down to avoid making crevices around the headlight.  Use your razor to cut away the excess tape crossing the lens.


  1. Wrap your sponge with a piece of your 500-grit dry sandpaper and sand the lens in a back-and-forth motion and never in a swirling hand movement. Change the direction of sanding every 10 seconds.


  1. Sand the lens until it turns totally opaque and has that silky smooth feel.


  1. Get your microfiber rag and wipe off the headlight to reveal your work. When it’s okay, rinse the light with water.


  1. Get your pitcher and fill it with water. Then add your liquid detergent and soak up the pieces of 1000-grit and 2000-grit of sandpaper.


  1. Fill in your spray bottle with liquid detergent and water solution you just made. Spray your headlight with this solution.


  1. Wrap your sponge with 1000-grit sandpaper and sand the lens, spraying it with the solution from time-to-time. Continue to sand until it’s has the smooth feel.


  1. Wash and rinse the lens, then ready your 2000-grit sandpaper. Sand in the same manner as you did in step #8.


  1. Smear the headlight polish of your choice all over the lens. Remember to smear the lens with polish in an even manner. Polish the lens in the same direction as you sand it, using only medium pressure.


  1. As you attain the desired look of polish, wash it with water and detergent solution. Rinse and dry the lens totally.


  1. Rub it with alcohol using some of your unused microfiber rag. Follow rubbing with sealer—again—using an unused microfiber rag.


  1. Repeat steps 1-12 to the remaining headlights. Bask in the quality of your finished task.
