I'm getting my money's worth out of this canning lid! Learn how to inspect and test canning lids to save yourself a lot of money. Each crossed out date is one time used. I have chicken broth in it now. #canstr #pressurecanning #canning

Yep, as long as there's no dents and the rubber is clean, they're still good! I reuse them too,
I also check that they still pop back automatically on their own. I also will round the edges if someone pried up on the edge and flattened it. I have seen the gasket material flatten out so much you could start to see metal. I don't use those either.
