Method 1: We can scald it with hot water, and it will come off as soon as the water is not too cold. Never wait until the water is cold, but when it is a little hot, it will come off without leaving any traces.
Method 2: We can use alcohol, gasoline or diluent such as nail polish and hand cream to help remove it easily and completely. Tear off a layer of paper on the surface of the label and smear it with alcohol or gasoline, then rub it on the surface by hand to make it fully saturated, and finally wipe it off with a cloth.
method 3: we blow the label with a hair dryer, and when it gets hot for a while, we gently peel it off with our hands, and there will be no residual glue.
method 4: drop a few drops of wind oil essence or apply cool oil on the label glue, and it will be easy to peel off after a while, otherwise the label will fall off by itself the next day.
method 5: you can put some hand cream on it and take it off later. Or put toothpaste on it, and it will tear off after a while and there is no trace.
