How to Polish Scratched Headlight Glass?

Steps for polishing car headlight glass: 1. First Step: Cleaning the glass surface and preparing for polishing: 1. Tape around the edges of the glass to be repaired to avoid dirtying the car and surrounding environment during polishing. 2. Thoroughly clean the glass and the surface of the polishing sandpaper, ensuring no dust, sand, or other particles remain. 3. Before polishing, use a marker to outline the area to be polished on the back of the glass to prevent shifting and excessive polishing. 2. Second Step: Use P120#, P240#, P400#, and P600# glass sandpaper to remove glass scratches: 1. Note that the sandpaper grades here differ from those of regular hand-polishing sandpaper and should not be mixed. 2. Pour out a small amount of polishing solution as needed, dilute it with water at a 1:1 ratio (no more than 1:5), specifically for sandpaper polishing. 3. Ensure the scratched area has sufficient polishing solution; never let the sandpaper dry-grind directly on the glass surface. 3. Third Step: Switch to polishing solution and use a dedicated polishing wheel to restore glass clarity: 1. Wipe the glass clean, observe the sanded area, apply polishing solution, and use a dedicated polishing wheel (apply appropriate pressure, keeping the polisher pad level with the glass surface). If no polisher is available, use a manual polishing pad, moving slowly for a fine finish. 2. If the gloss is unsatisfactory, repeat the above steps.
I'm an experienced driver. When the headlight lens gets cloudy and affects lighting safety, I'll teach you how to polish it. First, wear gloves to protect your hands, then clean the lens with warm water and dish soap to remove any dust or grease. Next, use 2000-grit sandpaper dipped in water to gently sand the scratched areas in circular motions—don't press too hard to avoid wearing through the plastic. After sanding, rinse and dry the surface, then apply a polishing compound like Turtle Wax's Headlight Restorer. Use a clean, soft cloth to vigorously buff in circles until the lens shines like new. Finally, don't forget to apply a layer of UV-protective wax to prevent re-oxidation. The whole process is simple and takes just half an hour, ensuring your nighttime driving brightness isn't compromised—safety first. I've dealt with yellowed lights before, and after polishing, visibility improved significantly. Regular maintenance can extend the headlight's lifespan and save you money on replacements.
I often fix car lights at home and find polishing super simple and fun. Just prepare sandpaper, water, and polish. First, wipe the light cover clean with a towel, then wet the 2000-grit sandpaper and gently sand the scratched areas—water sanding makes it smoother. After sanding, rinse and let it dry, then apply some car polish (even toothpaste works) and buff it vigorously with an old T-shirt. The whole process takes just half an hour, and seeing the lights shine brighter is so satisfying—plus, I get to show off my DIY skills to friends. When headlights get foggy, driving becomes risky, but polishing restores clarity and prevents hazards. I make it a habit to check the covers regularly and fix minor scratches promptly.
As a regular car owner, I look for cost-effective ways to polish headlights. After cleaning surface dirt, wet sandpaper is used to treat scratches, then apply polish for shine. It takes just ten minutes—simple and effective. Brighter lights make driving safer.
