Pickle barrel stories reminds me of the story of the farm family that found a pickled kitten at the bottom of a 25 gallon crock after they'd consumed all the sauerkraut.
Wonder how kraut juice would do a rust remover?
Obviously you never packed kraut or you'd know the only was a kitten got at the bottom of the crock would have been deliberate human action.
Kraut juice is salt brine, and an excellent Rust MAKER, not a remover.
I'm still amazed I love kraut given the tons I cut and packed in kid prison.
"Oh, we're so fortunate this year boys, Farmer Insert Name is bringing us a truck load of cabbage" was a strobing alert for Phil to be lost. Somehow, they always hunted the retarded kid up who walked the damn troth in the new winter boots set aside just for Kraut packing.
