It can be difficult to remove a stuck mason jar lid but there are several methods that can help make this process easier. You can try soaking the jar in hot water, gently tapping around the edges of the jar onto a flat surface, and using tongs or pliers to grip the edge of the lid and twist it off gently. It may also help to place a rubber band around the jar lid before attempting these methods for added traction and leverage while twisting off the lid.
