Yes, you absolutely can wax headlight lenses.
Applying wax is a technique often used to provide a temporary layer of protection on headlight lenses, particularly after they have been cleaned or restored to remove cloudiness or yellowing.
Why People Wax Headlight Lenses
Wax, like car wax, is applied to create a barrier between the plastic lens surface and environmental elements. This protective layer can help shield the lens from:
- UV Rays: A major cause of headlight yellowing and oxidation.
- Road Grime and Dirt: Makes the surface easier to clean.
- Environmental Pollutants: Helps maintain clarity.
How to Wax Headlight Lenses (Based on Reference)
As shown in the provided reference clip from a video titled "Clean and restore faded headlights with toothpaste protect with wax", applying wax is part of the process:
- Clean/Restore First: Headlights are typically cleaned or polished (like with toothpaste or a dedicated cleaner) to remove oxidation and restore clarity.
- Apply Wax: A wax, such as carnauba wax, is then applied to the clean, dry lens. The reference specifically demonstrates applying "a generous layer of the carniva wax and work it into the headlight lens in a circular motion and then back and forth".
- Buff Off: Once the wax hazes, it is typically buffed off with a clean microfiber cloth to leave a smooth, protected surface.
This process helps to lock in the clarity achieved through cleaning and adds a sacrificial layer that takes the brunt of environmental exposure instead of the plastic itself.
Considerations When Using Wax
While waxing headlights is simple and provides temporary benefits, it's important to know:
- Temporary: Wax protection doesn't last as long as dedicated automotive clear coats or plastic sealants designed specifically for headlights.
- Regular Application: To maintain protection, you would need to reapply wax periodically, similar to waxing your car's paint.
Applying wax after cleaning or restoring your headlights, as demonstrated in the reference, is a valid method for adding a layer of temporary protection to help preserve their clarity.
