Removing Gummy Glue on a Glass Jar
How many time have you tried to get that sticky label off of a jar? You soak and scrub and still wind up with sticky places that never seem to come off. Try this trick: Put the jar in the microwave with a damp towel over it. Microwave on low and check every 30 seconds to see if the heat is softening the glue. Then you should be able to pull the label off.
