To get the labels off commercial jam jars use hot water. Heat water in the kettle as the water from the hot tap isn’t hot enough to soften the glue. Pour the hot water in the sink but not directly on the jars with a few drops of detergent and soak for a couple of minutes then wearing rubber gloves and a vege knife try to peel the labels off. Stubborn glue residue can sometimes be removed with cooking oil. Jar lids can be reused to seal the jars. Steralise using the same method as for preserving jar seals.
