When re-using Ball jars, do you guys rinse with just soap and water? dishwasher? just water?
I read somewhere that the smell of the tobacco can retain/linger on the rubber part of the used lids. So a lot of people replace the lids so that there tobacco is not infused with another tobacco's smell. People also replace the lids, because the rubber can wear out. Lids are pretty cheap to buy. You could run the lids through the dishwasher, but more than likely the rubber would be damaged from the heat.
Once the lid is used and flattened on the jar, then removed, it is compromised, if only slightly. I reuse my lids for my 'open tobacco jars', but if I'm jarring up stuff for the cellar, I always use new lids.
