1. Pour nail polish remover onto the area with offset printing.

2. Use a sponge to wipe the area where nail polish remover was poured. Residual offset printing can be easily wiped off.

3. Pour alcohol on the area with offset printing.

4. Use a sponge to wipe the area where the alcohol has reached, and you can easily wipe off the remaining offset printing.

Other methods:

1. Use a paper towel dipped in some alcohol (industrial alcohol is best, but medical grade is acceptable) 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 quickly and easily, which is more effective than spraying essence.

3. Use hand cream. First tear off the printed product on the surface, then squeeze some hand cream on it, rub it slowly with your thumbs, and rub it for a while to remove all the remaining glue. Just a little slower. Hand cream is based on oily substances, and its properties are incompatible with glue. This feature is used to remove glue.
