Cleaning your car headlights is an important step in maintaining the overall appearance and functionality of your vehicle. 

Over time, headlights can become cloudy and discolored due to exposure to the elements and road debris, reducing the amount of light they emit and making it difficult to see while driving at night. 

Fortunately, cleaning your headlights is a simple task that can be accomplished with a few common household items, including WD-40.

In this article, I have provided a comprehensive, step-by-step guide on effectively cleaning your car headlights with the power of WD-40.

  • Microfiber cloth or sponge
  • Car soap or specialized headlight cleaning solution (optional)
  • Carnauba wax or UV protectant (optional)
  • Water

Steps:

  1. Find a nice, well-ventilated spot to park your car and let your headlights cool down.
  2. Grab a microfiber cloth or a sponge, and give your headlights a quick wipe to remove any loose dirt or debris. You can use some soap or a cleaning solution for this.
  3. Spray some WD-40 onto a clean microfiber cloth or sponge.
  4. Gently rub the cloth or sponge over the headlight, using circular motions to work the solution into the surface. Make sure you cover the entire headlight, especially any cloudy or discolored areas.
  5. Let the solution sit on the headlight for a few minutes to give it time to work its magic.
  6. Use a clean microfiber cloth or sponge to wipe the headlight clean, and remove the solution and any dirt or grime that’s been lifted.
  7. Repeat steps 3-6 on the other headlight.
  8. To keep your headlights looking shiny and new, apply a coat of carnauba wax or a UV protectant.
