Are your headlights looking hazy, yellow, or oxidized? Not only do foggy headlights make your car look old, but they also reduce visibility and safety while driving. The good news? You can restore your headlights to their former glory with this simple, budget-friendly method that costs just $10 per headlight and lasts permanently—no more temporary fixes with toothpaste or vinegar!

Follow this guide to achieve crystal-clear, long-lasting headlights in no time.

Why Do Headlights Become Foggy?

Over time, the clear coat on your headlights gets worn down by UV rays, debris, and weather exposure. This causes oxidation and a cloudy appearance. Unlike temporary fixes that only clean the surface, this method adds a new UV-resistant clear coat, protecting your headlights for years to come.

What You’ll Need:

• 400 grit sandpaper (for heavily oxidized headlights)
• 600 grit sandpaper
• 2000 grit sandpaper
• Spray bottle with water
• Isopropyl alcohol
• Painter’s tape
• Scissors
• Garbage bag
• Paper towels
• UV-resistant, non-yellowing clear coat spray (plastic-safe)

Step-by-Step Guide:

1. Prep the Area

• If possible, remove your headlights from the car to make the process easier.
• If removing isn’t an option, tape off the area around the headlight with painter’s tape.
• Use a garbage bag to cover the car’s paint, securing it with tape. This prevents over-spray when applying the clear coat.

2. Wet Sand the Headlight

• Start with 400 grit sandpaper for heavily oxidized headlights. For less-damaged lenses, you can begin with 600 grit.
• Wet the sandpaper and the headlight with water from your spray bottle.
• Sand in a circular motion, keeping the surface wet at all times.
• As you sand, you’ll notice a milky residue—this is the oxidized layer coming off.
• Finish by sanding horizontally to create fine scratches that help the clear coat adhere better.

3. Move to Finer Sandpapers

• Switch to 600 grit sandpaper and repeat the process. Press slightly harder this time to smooth out the surface.
• Finish with 2000 grit sandpaper for a polished look. Be gentle, as this is just to refine the surface.

4. Clean the Surface

• Rinse the headlight with water and wipe it down with a paper towel.
• Use isopropyl alcohol on a lint-free paper towel to remove any oils or residues. This step ensures the clear coat bonds perfectly.

5. Apply the Clear Coat

• Shake the clear coat spray can well and follow the instructions on the label.
• Apply light, even coats across the headlight. Avoid heavy coats to prevent dripping.
• Wait five minutes between coats and apply at least three coats for maximum durability.

6. Optional: Wet Sand and Wax

• If you notice an orange-peel texture after the clear coat dries, you can lightly wet sand the surface with 2000 or 3000 grit sandpaper for a smoother finish.
• Buff the headlight with a microfiber cloth and apply a thin layer of car wax for added shine and protection.

The Final Result

After letting the clear coat cure for 24 hours, your headlights will look brand new! The UV-resistant coating will keep them clear and bright for years to come, enhancing both your car’s aesthetics and its resale value.
