Methods for removing stubborn stains left by adhesive tape or trademark stickers with glue on the back: 1. Use hand cream to remove the adhesive. Hand cream contains a certain amount of surfactant, which can quickly penetrate between the sticker and the surface of the object, thereby achieving the purpose of removal. ? 2. For sticker marks on the surface of hard objects, you can apply nail polish remover on the surface of the object, and then wipe it gently with a soft cloth. Because nail polish remover is highly corrosive, it cannot be used on surfaces that are afraid of corrosion, such as painted furniture, laptop casings, etc. 3. Use industrial alcohol or gasoline to remove these traces. Likewise, if you have expired perfume or astringent, you can use it instead of alcohol. Of course, items with tape traces must not be afraid of alcohol corrosion. 4. Fengyoujing is also a good thing. Generally, put some Fengyoujing on the paper sticker, wait a few minutes and then tear it off with your hands. 5. The safest and best way is to use alcohol. Generally, if there is no alcohol, it is also possible to use your own liquor, but the effect will be worse. 6. If none of the above materials are available, you can try using white acetic acid. The vinegar used for cooking at home also has a certain effect, but the effect is not very strong. 7. Removing traces of non-paper self-adhesive prints, such as PVC, PE and other materials, is relatively simple and can be achieved by wiping and cleaning. However, some anti-counterfeiting self-adhesive printed labels and special printed self-adhesive labels may be difficult to remove. It can only be dealt with according to the specific situation. The key is to recognize the characteristics of the adhesive used in self-adhesive labels.
