Magnet, did you ever find anything more about rust prevention in the presence of Chloride Salts? I just covered corrosion in one of my classes and there is no doubt that the presence of a salt at the surface of steel greatly increases the chances of oxidation. Apparently some products use Zinc as a "sacrificial anode" to shed electrons instead of the Iron in the steel, if you have found a reliable way to removed these dissolved salts from our steel I am all ears!
good from far, far from good.
