The Risks of Washing Canning Jars in a Dishwasher
When canning jars are washed in a dishwasher, they are exposed to extremely high temperatures (usually between 140°F and 180°F) and harsh detergents. This can cause the following problems:

The Benefits of Hand Washing Canning Jars
Hand washing canning jars is a safer and more effective way to clean them. This method allows for gentle cleaning and thorough rinsing, reducing the risk of damage to the jar’s seal and lid. Hand washing also enables you to inspect the jars for any damage or imperfections before using them for canning.
