There are two easy ways to get labels off jars. One is with nail polish remover, which is a little smelly. The other is our preferred method: hot water and olive oil. First, peel off as much of the label as you can with your fingers. Then get some really hot (but not boiling) water and fill the jar with it, which will start to melt the adhesive from the inside. After a few minutes, dump out the water and use a rag or paper towel dipped in olive oil to gently scrub the label away. It works every time!
