Clean the glass thoroughly by using a clean cloth to remove dust and debris from the windshield. Wait for the glass to dry completely before starting the scratch repair. Prepare a clean, lint-free cloth and dampen it with warm water. Then wring out the cloth until it no longer drips. Squeeze a pea-sized amount of toothpaste onto the cloth. Be careful when applying the toothpaste, as the amount is crucial. If it's not enough, you can always add more later. Use the toothpaste-covered cloth to rub the scratched area on the windshield. Rub in small circular motions for about 30 seconds. Take another clean cloth, wet it with water, and wring it out as much as possible. Wipe the area you just treated again.

I usually enjoy fixing minor issues with my car myself, like small cracks on the windshield, without needing to visit a shop. The method involves first purchasing a repair kit from an auto parts store or online, which typically includes resin, a syringe, a UV lamp, and other small tools. Start by thoroughly cleaning the glass, using alcohol to remove dust and grease, especially around the crack. Then, apply a fixing film to secure the syringe and slowly inject the resin into the crack. After injecting the resin, patiently wait for it to seep into the crevices. Finally, use the UV lamp to cure the resin for about ten minutes, ensuring it hardens completely. The entire process should be done in a shaded area, as strong sunlight can affect the results. DIY repairs usually cost just a few dozen dollars but are only suitable for cracks smaller than a coin size; larger cracks require professional attention. Regularly checking the windshield to prevent small cracks from expanding can save a lot of trouble. Before starting, it's best to watch tutorial videos to ensure the steps are followed correctly.

Windshield repair depends on the specific situation. Small scratches or minor cracks can often be handled with DIY methods. The process is straightforward: first, clean the glass thoroughly to remove any debris; then, use the tools in the repair kit to inject specialized resin into the crack, ensuring it fills the gap completely; afterward, cure the resin with a UV light to form a protective layer. These materials are affordable and readily available on e-commerce platforms or at auto parts stores. However, if the crack is deeper than a few centimeters, DIY repairs may not be effective and could even worsen the damage, in which case professional repair services are necessary. For safety, always test the repaired windshield's strength before driving, especially at high speeds. Don't overlook minor damage—exposure to wind and sun can worsen it over time. Regular maintenance can extend the windshield's lifespan and enhance driving safety.

I once had a small crack on my windshield caused by a flying stone, so I tried to repair it myself. The process was quite simple: prepare the repair kit, clean the glass, apply the film, and slowly inject the resin. After letting the resin soak for a while, I used the included UV light to cure it, and finally polished the area. The whole process took about half an hour and cost less than 100 yuan. After the repair, the crack was barely noticeable, and it held up fine for several months. However, it's important to note that this method only works for minor damage; larger cracks require professional repair. Such DIY experiences are commonly shared on car owner forums, saving both time and money.
