1. Blow it with a hair dryer for a while. After heating, the glue will melt, so it can be peeled off easily. If there are still some indelible marks, you can smear them with wind oil essence, which will clean them up.

2. Wipe it with a paper towel dipped in alcohol, and it will be clean after several times.

3. Use acetone in the same way as above. The dosage is small and thorough, and the best thing is that it can remove these residual gums very quickly and easily, which is better than alcohol.

4. Use nail polish remover. Usage is the same as alcohol acetone. The effect is also very good. Nail polish remover does not require quality, but it is good and general, as long as it can wash off nail polish.

5. Use hand cream. Tear off the surface print first, then squeeze some hand cream on it and rub it slowly with your thumb. After rubbing for a period of time, all the rubber residue can be wiped off. Just slow down. Hand cream belongs to grease and its properties are incompatible with rubber. Glue removal is to take advantage of this feature.

6. Use banana oil. It is an industrial paint remover, and it is also easy to buy. The method is the same as alcohol acetone.

7. It is difficult to remove the sticky film that has been used for a long time. You can first use a hair dryer to heat and soften the film, and then use rosin water to wash off the residual glue on the glass.
