1. Take a cotton swab or cotton or toilet paper and dip it in gasoline or nail polish remover to wipe the label to achieve traceless removal.

2. Apply some hand cream on the label. It can be easily removed after a while without leaving any trace.

3. If it is a paper label, wipe it with warm water a few times to wet the label, then rub it with an eraser a few times, and the label and sticky substance will be wiped off.

4. Use a hair dryer to heat the label, and you can easily tear it off without leaving anything in vain. If it is still a little sticky, wipe it with 95% alcohol (you can also use 75% alcohol) and it will be OK.
