Why Do Mercedes-Benz Headlights Become Cloudy?

Even with advanced lighting technology—like LED, projector-beam, and intelligent lighting systems—headlight lenses are typically made from polycarbonate plastic. This material is durable, but it can become cloudy because of:

UV ray exposure
Oxidation from air and moisture
Road contaminants such as salt, dust, and tar
Micro-scratches from debris
Washing chemicals or harsh cleaners

Understanding these causes can help you choose the right cleaning method and prevent future damage.

How to Clean Mercedes-Benz Headlights: Step-by-Step Guide

This DIY-friendly process works for most modern Mercedes-Benz models, including the C-Class, E-Class, GLE, GLS, GLB, and more.

Start with a Thorough Cleaning

Before tackling oxidation, remove surface dirt.

What you’ll need:

Mild car shampoo
Soft microfiber cloth
Water

Steps:

Rinse the headlights with water.
Apply car shampoo using a damp microfiber cloth.
Rinse and dry thoroughly.

This prepares the surface for deeper cleaning.

Mercedes-Benz Frequently Asked Questions

Use a Headlight Restoration Kit (Recommended Method)

The safest and most effective approach is using a restoration kit, which includes sandpaper, polish, and a protective sealant.

General steps:

Mask off the surrounding paint with painter’s tape.
Wet sand the headlight, starting with the lowest grit and moving to finer grits.
Polish using the provided compound to eliminate haze.
Apply UV sealant to prevent future clouding.

A high-quality kit protects your lighting system and provides long-lasting clarity.

Use Toothpaste as a Quick Fix (Short-Term Solution)

If you need a temporary improvement, whitening toothpaste can help reduce haze.

How to do it:

Apply toothpaste to the headlight.
Use a soft cloth to scrub in circular motions.
Rinse and dry.

Note: This method works but does not offer long-term UV protection.

Apply Baking Soda and Vinegar (Alternative DIY Method)

This natural cleaning option offers mild abrasive power.

Steps:

Mix baking soda with a small amount of vinegar to create a paste.
Rub the paste onto the lens using a microfiber cloth.
Rinse and dry the surface.

Useful for minor cloudiness, but not ideal for heavy oxidation.

Protect Your Headlights After Cleaning

Clear headlights stay bright longer when protected.

For the best results:

Apply a UV protectant every few months.
Avoid harsh chemicals when washing your vehicle.
Park in shaded or covered areas whenever possible.
Consider professionally installed protective film.

When Should You Let Certified Mercedes-Benz Technicians Handle It?

DIY cleaning works well for mild to moderate oxidation, but professional service is recommended when:

The headlights remain cloudy after cleaning
Cracks or deep scratches are visible
Moisture appears inside the lens
Your model features advanced lighting systems, such as MULTIBEAM LED or Digital Light

Mercedes-Benz lighting technology is intricate, and our trained technicians at Mercedes-Benz of Arrowhead use specialized tools and products designed specifically for these components.
