# How to Open a Rusted Jar
Jar lids tend to rust when left in a damp, humid atmosphere. Most modern containers are treated to resist rust, but this is not the case for many older jars. The problem is exacerbated in the case of a metal jar and lid, as rust will form on both the lid and the threading. Fortunately, you can open virtually any rusted jar by removing rust particles, lubricating the threading and using a rubber jar opener to get a firm grasp on the lid.
