How to make scratched car glass clear again?

Automotive glass scratches can be repaired using a specialized windshield repair agent. Here are the relevant details about repairing car windshields: 1. Precautions: Only the front windshield can be repaired because it is made of laminated glass, which generally does not suffer from large-scale cracking. Repairs are only possible under these conditions. 2. Types of glass damage: One type is bullseye or star-shaped cracks. Bullseye damage is circular, resembling a dent; star-shaped cracks radiate outward from the impact point, resembling a spider web. Generally, if the diameter of bullseye damage exceeds 3cm, the damage is too severe to repair. Star-shaped cracks with diameters exceeding 30cm are very difficult to repair, and even if repaired, there is no guarantee of quality or appearance.
Here's how I do it: First, identify the cause of the blurred car glass. The exterior might have oil film, scratches, or dust buildup, while the interior could be foggy or have fingerprints. Start by cleaning—use glass cleaner with newspaper for wiping. For stubborn oil film, spray on a specialized cleaner, wait a few minutes, then wipe it off. For scratches, apply toothpaste with an old toothbrush and gently scrub, then polish with a soft cloth—it works better than you'd think. Finally, apply a rain repellent to prevent water droplets from lingering. I usually maintain it once a month, and the driving visibility improves significantly—safety first. Remember, avoid using hard objects to scrape, as small scratches can worsen and become a bigger issue.
My experience with dealing with blurry glass involves a few steps: First, wash the outside, apply a paste of toothpaste or baking soda, rub in circles with a cloth, then rinse with water. For heavy grease, buy a degreaser, spray it on, let it sit for five minutes, then wipe with a sponge. For the inside, use alcohol wipes to remove fog and prevent fingerprints. If the wipers are old, replace them immediately as they not only fail to clean properly but can also damage the glass. Park away from trees and construction sites to reduce dust accumulation. After washing the car, take a moment to wipe the glass—maintaining good habits saves time and ensures safety. Learning to do it yourself saves a lot of money, and the tools needed are just common household items like towels and newspapers.
For blurry car windows, try these products: Oil film cleaner spray and wipe to remove grease; Nano coating agent applies once and lasts three months without water stains; Scratch repair kit handles minor scratches. Daily use neutral glass cleaner with a soft cloth to avoid strong acids or alkalis damaging the glass. Choose anti-glare window film for less reflection and clearer vision at night. Simple to operate—just follow the instructions, and tools are readily available at supermarkets. Proper maintenance extends the glass's lifespan, ensuring a clear view and better mood while driving.
