Alcohol removal method. Dip a soft cloth with 95% alcohol, and then gently wipe the adhesive, the adhesive will become soft and easy to fall off, and alcohol will generally not damage the surface of plastic parts or car paint. But sometimes it is found that alcohol is not very effective for some stickers. This can be achieved by dipping a soft cloth in a little gasoline and gently wiping the sticker. At this time, it should be noted that gasoline has a "dissolving" effect on a certain plastic or paint, so it must be used carefully: either gently wipe it in an unimportant place first and use it if there is no problem; But be careful not to use too much gasoline, as short as possible!
