Car headlight glass scratches can be treated by: 1. Toothpaste Polishing: Toothpaste contains abrasive particles. Apply toothpaste to the headlight, then use a clean towel to polish in circular motions before rinsing with water; 2. Polishing Repair: Clean dust and dirt from the headlight surface, sand with water sandpaper, remove the powder after sanding, and use a towel dipped in polishing wax to polish in circular motions. Car headlights consist of the headlight assembly, onboard computer, and light sensor, characterized by low power consumption, high brightness, and long service life. The functions of car headlights are: 1. Accurately illuminate the road ahead; 2. Improve safety during night driving; 3. Avoid affecting the vision of oncoming drivers.
As a DIY car maintenance enthusiast, I find dealing with headlight lens scratches quite straightforward. For minor scratches, toothpaste or specialized polishing paste works well—first clean the headlight surface, apply a small amount of toothpaste, and gently rub in circular motions with a soft cloth or sponge for a few minutes before rinsing with water. Repeat this process a few times, and the scratches will gradually fade. For deeper scratches, I recommend purchasing a professional repair kit, which costs just a few dozen yuan and includes various grits of sandpaper and polishing compounds—just follow the instructions step by step. Be careful not to over-polish to avoid damaging the plastic lens. After repair, the headlight will regain clarity, improving nighttime driving safety. When washing your car, use mild soapy water and avoid stiff brushes to prevent new scratches. DIY not only saves money but also teaches useful skills—it's definitely worth trying.
