You’re saying you reuse yours? My wife uses new every year.
I’ve reused them. Check them carefully for any defects. I’ll reuse lids from green beans or peas (less acid damage) on tomatoes or pickles the next year. Some lids might last 2 or 3 years with rotation like that. However, always double check and be 100% sure the lid has “popped” before storing. Even though I’ve reused lids I’ve only had a failure to seal rate of probably less than 1%. Those that did fail were simply stuck in the fridge and eaten first.
If they’re not dented at all, and the rubber seal looks fine, then yes, I do.
No problems to date.
I think a lot of time you need new lids because someone pops it off with an opener and bends it a little. In that case, it won’t re-seal, of course.
