I tried citric acid.  I have this awful tendency to get interrupted, and 
once I left a tool in a fairly strong solution for about a week.  When I got 
back to it, the tool had kind-of a frosted white surface, rather than the 
specular reflection of tool steel.  I still use it, but I'm a lot more 
careful now.

I like electrozapping tools; I've found that if I get them out and clean 
them right away under running water with a grey or white 3M pad, then dry 
and wax promptly, I have good results.  I also have some control over 
patina - if I rub hard for a longer time, I get a brighter surface; if I rub 
less, it's still flat and smooth, but more character and patina remains. 
You can tell it's been zapped of course, but it's quantum levels better than 
rustoleum and belt sanding.

That said, what kind of surface does Evaporust leave?  Does it leave a 
bright, just machined look?  Does it preserve any character?  Before and 
after pictures would be nice, if available.

Eager to learn as always,
