Electrolysis style rust removal

Worth knowing but I'll stick to washing soda, kinder to your hands and eyes.

Rusty mild steel, especially if pitted, after the hydrochloric acid and washed will rust like mad in damp weather. It is best to neutralise the acid with a touch of weak caustic soda then water, then dry then brush on phosphoric acid. The grey coating this gives is some protection against futher rust.

Not as cheap as some of the other solutions offered, but not terribly expensive either, and being reusable, a bottle seems to last for years is Evapo-Rust.
It is incredibly effective and completely non-toxic, it can safely be poured down the domestic drain once one is ready to dispose of it nor is it harmful to ones skin.

A pile of rusty castings for a pair of Stuarts, a 10V and 10H, I was given some time back:

The boxbed after a couple hours in Evapo-Rust then a rinse in hot water. It looks like a brand new casting;

Even the pile of rusty nuts and bolts in the top left corner of the first image cleaned up amazingly after a few hours soak, unfortunately I didn't think to take a photo at the time.

Evapo-Rrust is carried by many of the larger hardware stores in Canada, a web search indicates that it can also be obtained in the UK evapo-rust.co.uk

There has been lots of suggestions about different solutions for removing rust, one of which was molasses.

My copy of MEW finally arrived today and I was surprised to read an article about using a 50/50 solution of molasses for removing rust.

evapo-rust.co.uk looks rather good, but they're obviously ashamed of the price - I couldn't find any mention of it.
