There are many ways to remove the adhesive left by labels. We can use a rag with some alcohol to wipe it and rub it a few times and it will be clean. You can also use acetone to wipe, which is easier to use and more effective than alcohol. You can also use nail polish remover, which is also very effective. The nail polish remover does not need to be of good quality or just average. You can also use hand cream. First tear off the silver products on the surface. You can also squeeze some hand cream on it and rub it with your thumbs. The remaining glue will be rubbed off in a while.
