Can Rusted Rings on canning jars be removed?
I have about a dozen glass jars with food contents in them and the rings were left on and they have rusted on the jars. These were my Mom's jars, she recently passed away, and I would really like to save them if I can. I know that the food inside is unsaveable, and I'm always careful to avoid spores and such. Is there a way to loosen and remove the rusted on rings? Thank you all.
