I'm going to try the baking soda thing, but it'll be awhile before I have an empty pickle jar. If it works, I'll be sure to let you know.Yeah, I think it's the lids that hold the smell. I don't the imagine the glass jars retain any smell. Depending on the type of jar lid, maybe soaking it in baking soda water for a day or two and then letting it dry out really good. Don't know. Just have about 4 or 5 of those large bulk pickle jars on the storage shelf looking for a second life.
