Have you ever got something that had a sticker on it and you tried to take it off and it left some of the glue ? I'm going to show you how to take it off with a Cotten ball and rubbing alcohol. It is very easy to do.
Put a little bit of rubbing alcohol on the Cotten ball. Then keep rubbing the Cotten ball on the spot that has glue until it gone. That's all you have to do.
