Clean the area to be repaired with alcohol and glass cleaner, then blow out all the small glass debris. Use the positioning sticker from the repair kit to mark the spot, then apply the glass repair fluid. Prepare a syringe, pull it to the top, and seal the opening at the bottom for about 10 minutes. Press the repair fluid into the cracked area. After waiting for 15 minutes, replace it with a curing film and use a blade to squeeze out any air bubbles.

I often handle these minor issues myself. If there are shallow scratches on the car glass, I first try using regular toothpaste: squeeze a tiny amount onto a clean, damp cloth, gently rub in circular motions over the scratched area for a few minutes, then rinse with water to see the effect. If that doesn't work, I buy specialized glass polish from the supermarket, apply it as instructed, and gently buff with a soft sponge for about ten minutes—avoiding excessive pressure to prevent thinning the glass. For deep scratches, it's better not to take the risk, as they can worsen and impair visibility, making driving dangerous. After washing the car, I usually wipe the glass with a microfiber cloth to prevent new scratches—most scratches are caused by sand or hard particles, so prevention is far better than repair.

I suggest taking it step by step. First, clean the glass surface with warm water and a soft cloth to remove dust. Then, apply the glass repair paste by squeezing it onto the scratch and use the provided sponge to polish in one direction for ten minutes, maintaining even pressure. For minor scratches, repeating the process a few times might make them disappear. For deep scratches, it's best to stop and seek a professional shop as they have advanced equipment like resin filling or specialized polishing machines for safe and efficient repair. During the repair, wear gloves to prevent slipping and avoid dirtying the glass. For daily maintenance, use neutral car wash soap to reduce the chance of scratches, and park away from branches or roadside debris to prevent damage.

I focus on preventing scratches by only using a soft cloth and warm water to gently wipe the glass, never using paper towels or hard objects to scrape. I replace worn-out wiper blades immediately to avoid scratching the glass. For minor scratches, I try using toothpaste to rub and conceal shallow marks, without forcing a complete repair. For deep scratches or cracks that affect safety, replacing the glass is a more reliable and cost-effective solution. Regularly checking the condition of the glass is key to saving money and peace of mind.
