Use a tissue dipped in some alcohol (preferably industrial alcohol, but medical alcohol will also work) to wipe, and then rub a few more times to clean it. The method is the same as above. It uses a small amount and is thorough. The best part is that it can remove these residual adhesives very quickly and easily, even better than alcohol. The usage is the same as with alcohol or acetone. Nail polish remover doesn’t require high quality; good or average ones will work as long as they can remove nail polish. Tear off the surface print, then squeeze some hand cream onto it and slowly rub with your thumb. After rubbing for a while, the sticky residue will come off. It is an industrial agent used to remove paint and is also very easy to buy (available at paint stores). The method is the same as with alcohol or acetone.

I've dealt with similar situations before, and the adhesive residue shadows left after removing car decals are actually not difficult to resolve. You can try using a hairdryer to heat the remaining adhesive marks, while gently rubbing with your fingers as you heat, slowly rolling it up like removing transparent tape. If there's still a sticky feeling, apply makeup remover or cooking oil and let it sit for 15 minutes before wiping in circles with a soft cloth. For a more meticulous approach, you can use a specialized adhesive remover spray—spray it on the adhesive marks, cover with plastic wrap for half an hour, then gently scrape with the edge of a bank card. After treatment, remember to thoroughly clean with car wash soap, and it's best to apply a layer of wax to protect the paint. During regular car washes, pay extra attention to this area, as adhesive marks tend to become more noticeable in areas with more sunlight exposure.

Last time when I removed the sticker from my car's rear window, it also left adhesive marks. I found that the hot compress method works quite well. Soak a thick towel in hot water, wring it out, and apply it to the adhesive residue for 5 minutes to soften it. Then, add a couple of drops of essential balm or toilet water, and scrub in one direction with an old toothbrush. Avoid using steel wool as it can scratch the car paint! You can also buy a bottle of orange essential oil spray from the supermarket—it's effective and a natural solvent that's gentle on the hands. If the paint feels rough after cleaning, squeeze some white toothpaste as a polishing agent and gently rub it once for an instant shine. Remember to deal with the adhesive marks immediately after peeling off the sticker, as they become harder to remove after prolonged sun exposure.

Three simple tricks can solve this problem: First, use an eraser to vigorously rub off the adhesive marks—large office erasers work best. Second, apply a thick layer of hand cream on the adhesive residue to break it down with oils. Third, mix kitchen vinegar with water in a 1:1 ratio, spray it on, cover with plastic wrap for half an hour, then wipe it off. After treatment, be sure to rinse thoroughly with clean water, as residues can corrode the car paint. For old, blackened adhesive marks, it's recommended to visit a car detailing shop for polishing—spending around a hundred bucks can restore a smooth paint surface.
