Apply a small amount of solvent (such as thinner) to a cloth and wipe gently to avoid damaging the paint. First, try using wax for polishing, preferably automotive beauty wax. Be mindful of the pressure during polishing to prevent over-polishing and damaging the paint. For deeper or more stubborn marks, a polishing machine may be necessary to avoid excessive manual scrubbing. If wax is unavailable, try using a mild abrasive toothpaste, which can effectively remove minor marks.

When someone else's car paint gets smeared on my car, as a long-time car owner, I prefer to handle it myself. First, rinse the surface with water to see if the stain is just on the surface. If it's a minor mark, I use a clay bar to gently rub the paint, along with a lubricant, to gradually remove the outer layer. For deeper marks, I use a polishing compound with a soft cloth for manual buffing—it works well but requires patience to avoid damaging the original paint. I've also tried using regular toothpaste as a temporary solution; applying it and rubbing for a few minutes can temporarily cover the mark. If the area is large or deeply embedded, I take it to a professional shop for repainting to avoid making it worse and more expensive. Remember to take photos afterward for evidence to avoid disputes, and always leave enough space when parking to reduce the risk of scratches.

In this situation, I first calmly check the size of the scratch. Home DIY methods work quite well: take a soft cloth, dip it in some car wax or polishing compound, and gently rub in circular motions for a few minutes to see if the paint stain loosens. Avoid using hard brushes or vinegar-based solutions, as they can easily leave scratches. If a clay bar is handy, just spray some lubricant and knead it repeatedly – the results are usually good. Cost-wise, you can handle it yourself by spending a few dozen yuan on products; if that doesn't work, a car wash shop might charge around a hundred yuan to deal with it. Meanwhile, notify the other party to communicate and negotiate, saving both hassle and money. Develop the habit of walking around your car for a quick inspection before driving to prevent issues in the first place.

I usually take a two-step approach: First, rinse with water and a neutral detergent to see if light scratches can be removed. If that doesn't work, buy a specialized paint stain remover, apply it, wait five to ten minutes, and then wipe it clean. Avoid scrubbing too hard to prevent damaging the original paint. If all else fails, take it to a repair shop where they can polish and restore it with professional tools. To prevent future issues, choose a spacious parking spot next time.
