How to Repair Aged Headlights?
2 Answers
Use a soft cloth to clean dust, dirt, and other debris from the surface of the headlights. It is recommended to use a professional car cleaning towel to avoid secondary damage to the lens. Wash the headlights with soapy water, avoiding detergent (which is highly corrosive to the lens), as soapy water is safe. After cleaning, polish the headlights with a clean soft cloth, then apply polishing wax or polish to enhance the brightness and gloss of the headlights for maintenance.
Headlight aging is a common issue. Having driven for decades myself, I've seen it many times. Yellowing surfaces not only affect illumination but also reduce nighttime driving safety. The repair isn't difficult - a simple method is using headlight polishing paste or a dedicated restoration kit for manual wiping. It's cost-effective with good results, just remember to handle gently to avoid scratching the lens. I've done this several times myself, and the light output improved noticeably after polishing. If severely aged with cracks or internal cloudiness, you might need to replace the lens or the entire headlight assembly. Regular cleaning and avoiding prolonged exposure to strong sunlight/rain are recommended. For safety, don't delay - address it early to ensure clear driving visibility. After all, dim lights can lead to accidents, and small problems become expensive when neglected.
