1. Fill up a sink with hot water. Alternatively, you can also use a basin or a bucket. Make sure that there’s enough water to submerge the glass jars in.
2. Add ½ cup of baking soda to the water. Mix well until the baking soda dissolves.
3. Remove the lid from the jar and submerge it in the water. See to it that the sticker labels are soaked.
4. Wait for about 20-30 minutes. This should be enough time for the baking soda to dissolve the glue in the label.
5. After several minutes, peel off the label from the jar. The glue should be dissolved by that time, and the label should come off easily.
6. To remove any remaining glue residue, scrub off the glass jar with a scouring pad or steel wool. Clean the jar with soap to remove any traces of baking soda and rinse with water. Air-dry or pat dry the jars with a clean towel.
