Lemon juice: aka citric acid and I'm told that some companies are using concentrated citric acid as an eco-friendly alternative to the acids they used to use to passivate stainless steel. No surprise the lemon juice works.<G>

otg, rust on stainless stanchions, etc. is usually the result of iron grains embedded by tools and dies during the manufacturing process. Passivating with acid basically allows the acid to eat out the iron grains, and once they are gone there will be no more rust.

In theory.<G>
