I found this on a list related to restoring antique clockwork.
There is a technique for removing rust by electrolysis that apparently
does not alter metal (except for brass).
The method uses washing soda (I believe that sodium carbonate) in warm water
with an iron positive plate and the negative attached to the object.
Has anyone heard about this or tried this on iron meteorites?
I imagine the reaction is
Fe02 + NaCO3 + energy -> FeCOn + O2 + NaOH
but my high school chemistry is pretty rusty (ouch!).
