1. Apply a thick layer of cooking oil on the label.

2. Leave it for 24 hours to allow the edible oil to fully penetrate into the label.

3. Try to get rid of tags. If it can be removed easily, proceed to the next step. If it sticks firmly, you need to repeat steps one and two.

4. After the label is removed, there may be a little glue left. You can apply some cooking oil and leave it overnight.

5. Wipe off the oil and glue, and then wash the plastic container in hot soapy water.
