What Causes Fine Scratches on the Headlight Cover?
2 Answers
Crazing can be caused by various factors, most commonly material issues. Without maintenance, it will turn yellow over time. Here are the details: Scratch Depth: The treatment of headlight scratches depends on their depth. If the scratches are very deep, they cannot be repaired, and the entire headlight assembly must be replaced. If the scratches are not severe or deep, a specialized repair agent can be used along with a polishing machine to polish the surface of the headlight cover. Polishing Technique: Polishing requires certain skills, as it involves controlling the pressure, time, and speed of the polishing machine. Excessive pressure, prolonged time, or too high a speed can make the headlight cover more blurry or even cause it to crack. In such cases, the headlight assembly must be replaced.
I recently noticed quite a few small scratches on my car's headlight covers, and upon reflection, it's mostly due to my careless car washing habits. I used to think that scrubbing directly with a hard-bristle brush or rough cloth was more convenient, but the repeated friction ended up scratching the surface. Small stones or sand particles lifted by the windshield wipers can also leave marks. Additionally, parking under trees where falling leaves or branches hit the headlight covers can cause fine scratches over time. Now, I've switched to using a soft sponge and professional car headlight cleaner, gently wiping after each wash to avoid excessive force. These seemingly minor oversights in daily maintenance can accumulate, leading to reduced light transmission and affecting nighttime driving visibility. The key to prevention lies in improving cleaning habits—don’t cut corners and damage the headlight covers for the sake of speed and convenience.
