Tools needed: hand cream and rag.
1, squeeze a little hand cream on the label adhesive.
2. Wait for half an hour after the hand cream is evenly applied. The purpose of this step is to make use of the characteristic that hand cream can dissolve organic matter.
3. Wipe it with a rag.
4. Knock hard sundries with your fingers to remove them.
5, so the label was removed without leaving a trace.
Note: If you don't have hand cream, you can use other skin creams.
