Effective way to remove glue

Alcohol
Dip a sufficient amount of 95% alcohol with a soft cloth, and then gently wipe the sticker, the sticker will be easily softened and peeled 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. You can use a soft cloth to dip a little gasoline and wipe the stickers lightly. At this time, it should be noted that gasoline has a 'dissolving' effect on certain plastics or paints. So be sure to use it carefully: either wipe it lightly on an unimportant place first, and use it if there is no problem; but be careful not to use too much gasoline, and the time should be as short as possible. Generally speaking, wiping the surface of the car body with gasoline for a short time has no obvious effect on the paint film on the surface of the car body. In this way, the stickers can be easily removed.
essential oil
