Removing labels from glass jars (and bottles) is very easy! Just use water and dish soap. I soaked them in the bathtub for 12 hours (while I was at work) and the labels, glue, and ink from the expiration date just wiped off with a sponge! I had one label give me trouble. For that one, I covered the glue with olive oil and let it set for 6 hours. Then the glue wiped off with a sponge- no problem!
