How to Clean Headlights

Clean Headlights

If your headlights are looking foggy, yellow, or hazy, it’s time to give them a proper clean. Clear headlights not only improve the look of your vehicle, but also dramatically increase nighttime visibility and driving safety.

In this guide, we’ll walk you through how to clean headlights using methods that range from simple household items to professional kits—ensuring your lights shine bright and stay road-safe.

Why Headlights Get Cloudy

Most modern headlights are made from polycarbonate plastic, which is strong but prone to UV damage, oxidation, and surface wear over time. Exposure to sunlight, road debris, and chemicals can cause headlights to become dull, yellow, or foggy.

What You'll Need

There are several methods for cleaning headlights, depending on the severity of the oxidation. Here's what you might use:

  • Microfiber cloths
  • Masking tape
  • Water and soap
  • Toothpaste (with baking soda, for light haze)
  • Vinegar and baking soda mixture
  • Headlight restoration kit
  • Sandpaper (800 to 3000 grit, for heavy restoration)
  • UV sealant or clear coat

Step-by-Step: Cleaning with Toothpaste

This is a great method for mildly foggy headlights. Here’s how:

  1. Clean the area around your headlights with soap and water.
  2. Apply masking tape around the headlights to protect your paint.
  3. Squeeze toothpaste onto a clean cloth and rub in circular motions onto the headlight lens.
  4. Let it sit for a few minutes, then rinse with water and dry with a clean cloth.
  5. Repeat if needed. For longer-lasting results, follow with a UV sealant.

Step-by-Step: Using a Headlight Restoration Kit

For more severe hazing or yellowing, a dedicated restoration kit provides professional-grade results. These kits typically include sandpaper, polish, and a sealant.

  1. Wash and dry the headlight thoroughly.
  2. Follow the instructions for wet sanding in progressive grit order.
  3. Use the polishing compound to restore clarity.
  4. Apply the included UV sealant to prevent future fading.

When to Replace Instead of Restore

In some cases, especially when the lens is cracked or deeply scratched, cleaning may not be enough. If your lights remain dim after restoration, it may be time to consider aftermarket headlights for a better, longer-lasting upgrade.

Preventing Headlight Damage

  • Park in a garage or use a car cover to limit UV exposure.
  • Apply a headlight sealant every few months.
  • Regularly wash your vehicle to remove debris and contaminants.

Upgrade Instead of Clean?

If your factory lights are still lacking in performance after cleaning, explore options like LED headlights for cars or LED headlights for trucks from ClutchBlaze for better brightness, energy efficiency, and modern style.
