How to Clean Yellowed Headlights?
2 Answers
The first step is to wipe them clean. Go to the supermarket and buy some blue low-tack masking tape to cover the edges of the headlights. Soak a piece of 1000# grit sandpaper in cold water for 10 minutes, then evenly rub the headlight housing, sanding back and forth in one direction. After wiping away the sanding dust, apply an appropriate amount of polishing compound/paste using a microfiber or flannel cloth to the plastic housing. If you want to prevent the headlights from yellowing again, you can also apply a protective coating yourself.
As a long-time car enthusiast, I have some insights into dealing with yellowed headlights. Yellowing is usually caused by UV rays or oxidation, which can affect nighttime driving visibility and safety. When cleaning, I always start with simple methods: first, soak a soft cloth in warm water with dish soap and thoroughly wipe the headlight surface to remove dust; then apply regular toothpaste (white kind works best) and gently scrub in circular motions with a soft toothbrush for a few minutes to break down deep-seated grime; rinse with water and dry with a clean cloth. Afterward, I apply a layer of headlight protectant to guard against UV rays and extend their lifespan. Regular monthly cleaning can prevent yellowing—never use hard objects to scrape, as this can cause scratches. If the results are unsatisfactory, you can try a dedicated car cleaning kit, which is affordable. Remember, headlight condition directly impacts safety, so address issues promptly.
