When I learned to can it was through the Illinois Extension Office and reading books. There was no internet. I was wondering how all the canning members here store their full jars? With or without the rings. I don't think there is a right or wrong way. I have learned to take them off. First, because I wash my jars after canning with soap and water. Second, because I wash my rings also because if there is any food that seeps out during the canning process and stays on the ring they will corrode and rust. I dry them carefully, let them set out for a while then put them in a plastic bag that hangs on the wall in my pantry. I used to string them and hang them in the pantry but that was a pain in the neck. Since I could can 38 jars, wide or regular, at a time I keep about 70 of each size. That way if jars are still cooling and have the rings on I am able to put another set on and into the canner.
