metmom :” I just leave them in the box.
It’s oxygen that makes things deteriorate so if the oxygen is kept down, it should be a problem.
Also, when I buy lids, I date the box with the purchase year and constantly rotate my stock.
Never had a problem with them.”
I was wondering if a “Food Saver”, or a vacuum process would add to the longevity of the rubber ring and prevent oxidation ?
That’s a good idea.....
Good idea, that’s another option!!
