Hi John, List,

I did not try Steve Schoner's sodium hydroxide recipe to remove rust from
iron slices but, as a chemist, I have not any argument against its=
 efficiency.
I just proposed a product that is cheap, safe for us and harmfull for the
meteorite, easily available and of very simple and direct use. After 2
minutes rubbing, your slice is, in principle, ready.
 It is difficult to evaluate the efficiencies and advantages(drawbacks) of
the 2 processes. I believe the more procedures we have, the better for our
iron preservation.
By the way, does the NaOH process attack Widmannst=E4tten patterns ?

Best wishes,

Zelimir
