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

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