RL I'm not sure exactly how it works either but it loosens the rust so a
RL lot of it falls off into the bottom of the vat. The rest rubs off
RL quite easily. Now that I've done more pieces though, I'm finding that
RL there are stubborn, left over, spots of rust. These are mostly in
RL crevices and are probably the result of the current simply flowing
RL through the clean metal along the path of least resistance. Still,
RL removing these shows how much labor and mess is being saved by having
RL 90% of it done while you are busy with other things.

RL It may be that you can cook all the rust off if you are patient. I'm
RL working with some irreplaceable and precious parts however so I'm not
RL taking any chances. The web site where I learned about this cautioned
RL against overdoing it and losing surface detail.

I am impressed. Are you simply removing the rust or somehow
restoring
the rusted metal. I do not understand how this works.


There is no risk of overdoing it, as what you are doing is converting
rust, not removing metal. If you had connected your piece to the anode
(+ pole), it would have been different.
