Well, I've been successfully canning for a few months using a Presto 23 quart and Ball wide-mouth quart jars. I've been leaving the bands on the jars for fear of the tops coming off, but the lids are sealed quite nicely so I'll be taking them off, washing, drying, and setting them to the side to prevent rusting.
Something I've noticed is that some of my bands have been coming out of the canner already rusted. I give everything a thorough cleaning before use and discard any bands that I see that have potential problems, but it still hasn't solved the issue entirely.
I've bought some extra lids just in case I run into problems with the ones that come with the jars, and I'm considering tossing the contents of the jars that had the rust problem.
Is anyone else having/had similar problems?
