Cloudy or yellowed headlights not only detract from your car’s appearance but also significantly reduce nighttime visibility, compromising safety. Road debris, UV radiation, and oxidation are common culprits behind this issue. Fortunately, restoring your headlights to their former clarity is a straightforward process you can accomplish at home. This guide will walk you through the steps to clean your headlights effectively, enhancing both your vehicle’s look and your driving safety.
To begin, gather the necessary materials to ensure a smooth and efficient cleaning process. Having everything on hand before you start will save time and frustration.
Materials You’ll Need
- Headlight Cleaner or Polish: Products like Meguiar’s Plastx are specifically designed for polishing plastic headlight lenses.
- Sandpaper (1000 grit): Fine-grit sandpaper is essential for removing the hazy outer layer.
- Orbital Sander (Optional but Recommended): While you can polish by hand, an orbital sander significantly reduces effort and time, providing a more even finish. A 5-inch orbital sander is a common and effective size.
- Polish Kit: Kits like the Vector VEC232 often include polishing cloths and compounds that work well with headlight restoration.
- Microfiber Cloths: For applying polish and wiping away residue.
- Water: For wet sanding and cleaning the lenses.
- Painter’s Tape: To protect the surrounding car paint from accidental scratches or polish.
- Optional Refreshments: While not essential for the cleaning process, having a beverage on hand can make the task more enjoyable, especially if you’re working on a warm day.
Once you have assembled your materials, you can proceed with the headlight cleaning process. Follow these steps for optimal results:
Step-by-Step Guide to Cleaning Headlights

Preparation: Washing and Taping
Begin by thoroughly washing your headlight lenses with soap and water to remove any surface dirt and debris. This ensures that you are working on a clean surface and prevents scratching the lens during sanding. After washing, dry the headlights completely.
Next, apply painter’s tape to the painted surfaces surrounding the headlights. This protective barrier will prevent accidental sanding or polishing of your car’s paint, keeping it safe from damage. Ensure the tape is securely applied to avoid any slippage during the cleaning process.

Sanding the Headlights
Soak a sheet of 1000-grit sandpaper in water for a few minutes. Wet sanding is crucial as it helps to reduce friction and prevents the sandpaper from clogging with plastic residue.
Using the wet sandpaper, gently sand the headlight lens in a circular motion. Apply light pressure and work in small sections. Spend approximately 5 minutes on each headlight, ensuring you cover the entire surface evenly. Initially, the lens will appear hazy, which is normal. This haziness indicates that you are effectively removing the oxidized outer layer. Continue sanding until the entire lens has a uniform, frosted appearance.

Polishing with Plastx
If using an orbital sander, attach a medium-thickness polishing cloth from your polish kit (like Vector VEC232) to the sander. Apply a small amount of Plastx polish to the cloth.
Turn on the orbital sander and begin polishing the headlight lens. Use even, overlapping strokes and medium pressure. Work on each headlight for about 5 minutes at a time. It’s beneficial to take short breaks between polishing cycles to allow the lens to cool down and to prevent overheating the plastic. Repeat the polishing process for a total of three 5-minute cycles per headlight, or as needed, to achieve the desired clarity. If polishing by hand, apply Plastx to a microfiber cloth and rub vigorously in circular motions, applying similar pressure and repeating cycles as with the orbital sander.

Final Cleaning and Admiration
After polishing, wash the headlight lenses with water to remove any remaining polish residue. Dry them with a clean microfiber cloth. Inspect your work and admire the significant improvement in clarity. While headlights may not look brand new, you should notice a substantial enhancement, often restoring them to approximately 90% of their original condition.
By following these steps, you can effectively clean your headlights, improving both the aesthetics of your vehicle and your nighttime driving visibility. Regular cleaning, as needed, will help maintain headlight clarity and ensure safer driving conditions.
