1. Dip some alcohol with a paper towel (preferably with industrial alcohol, or medical use) to wipe it, and then rub it a few times and it will be clean.
2. Use acetone. The method is the same as above. The dosage is small and thorough. The best thing is that it can remove these residual gums very quickly and easily, which is better than alcohol.
3. Use nail polish remover. The usage is the same as alcohol acetone. The effect is also very good. Nail polish remover does not require quality, good or average, as long as it can wash off the nail polish.
4. Use hand cream. First tear off the printed matter on the surface, then squeeze some hand cream on it, and slowly rub it with your thumb, rubbing for a while to remove all the sticky glue residue. Just slow down. Hand creams are oils and fats whose properties are incompatible with glues. Glue removal is to use this feature.
5. Use banana water. It is an industrial agent used to remove paint, and it is easy to buy (it is sold where paint is sold). The method is also the same as alcohol acetone.
