I've always been a DIY enthusiast, and I've tried using toothpaste for small scratches on my car. The best choice is the regular white paste—apply it to a soft cloth with a bit of water and gently rub in circular motions over the scratch. The principle is that toothpaste contains fine abrasive particles that can polish away surface oxidation marks. However, it only works for ultra-fine, hairline scratches; deeper ones won't budge. The results? From a distance, it looks okay, but up close, you can still see some marks, and the process requires a lot of repetitive rubbing. Afterward, make sure to rinse thoroughly, as the fluoride in toothpaste can gradually corrode the paint. Also, be extra careful with darker-colored cars, as uneven color differences may appear. Nowadays, I keep dedicated scratch wax in my car—much easier than toothpaste!

Last time I saw my neighbor squatting in the community polishing his car, and learned he was using toothpaste to repair scratches. I tried it too and found it quite skill-demanding. You need to first wash and dry the car, spray some water on the scratched area, then apply a pea-sized amount of toothpaste. The polishing requires controlled force - too hard and you'll damage the surrounding paint, too light and it won't work. You must use a lint-free microfiber cloth and polish for over three minutes. The most troublesome part is the thorough cleaning required afterward, otherwise residual paste will attract dust. Personally, I think it only slightly fades light scratches at best - don't waste effort on exposed white ones. Different toothpastes vary greatly in effectiveness too, with baking soda types being more damaging to paint than whitening formulas.

That tiny scratch on the rear bumper had me agonizing for ages. With a nothing-ventured-nothing-gained attitude, I tried toothpaste. Learned three key things in practice: must use traditional white paste toothpaste (gel types are completely ineffective); must keep the paint surface wet to avoid secondary scratches; and absolutely must apply car wax as a protective layer. The results were marginally better than nothing - reduced swirl marks by about 50%, but don't even think about deep scratches that catch your fingernail. Most frustrating part? Dark paint shows whitish rubbed marks that stand out worse than the original scratch. Honestly, should've just bought a $10 scratch repair pen from the start.

As someone who washes my car every week, I've used the toothpaste method several times. The safest option is to choose a fine-textured children's toothpaste, squeeze it onto a wet sponge, and gently rub the scratch in even circular motions. The key is to keep the surface moist, just like applying a screen protector to a phone—dry rubbing will definitely make things worse. After treatment, you must rinse it with running water three times; otherwise, those tiny particles can get stuck in the paint gaps. Honestly, the effect is quite limited, especially for scratches that are very visible in sunlight—it's basically useless and may even thin the surrounding paint. Now, I only recommend this method for fresh, unoxidized fine scratches. For scratches that have been there for over a week, it's better not to bother.

New drivers inevitably experience minor scratches in their first year. A friend taught me to use toothpaste for scratch repair. Based on personal experience, I advise everyone to pay attention: first, absolutely avoid using whitening toothpaste with particles—that stuff is too abrasive; second, don’t believe the online advice about using a toothbrush for cleaning, as the bristles can easily scratch the paint; third, work in a shaded area, as doing it under the sun causes the paste to dry too quickly and leave marks. I spent half an hour on it, and while the shallow scratches did lighten, I could still feel the dents when touching them. The most surprising thing was that two months later, the treated area attracted more dust than the surrounding paint, probably because the surface protective layer had been worn away.
