<div class="yiv5420979803MsoNormal">That whole business of chelation seems like a red herring, Dave, to mask what's probably a pretty simple formulation. I can't see how chelation would convert rust. Now a chelating agent might very well be used in the formula to bind or
isolate iron removed during the de-rusting process -- they list a chelating agent on their safety data sheet -- ,but a chemist wouldn't normally think of chelation and corrosion-reversal as the same thing.</div>

3.5-gallon pail with a parts basket strainer for a good price. The stuff isn't cheap, unfortunately. About $10-15/gallon is a decent price.

<div class="yiv5420979803MsoNormal"><span style="font-size:10.0pt;font-family:sans-serif;color:black;">Some people initially think Evapo-Rust is like naval jelly or one of the many other phosphoric acid-based rust treatments, a brush-on/spray on system. It's not.
It's a dilute, gentle amber watery fluid in which parts are immersed in for anywhere from hours to days. It works for a while until it gets black and exhausted, whereupon it's pitched for fresh. The black stuff, as best the chemist in me can guess, is reduced
iron as the oxide has electrons donated to it by Evapo-Rust converting it to elemental iron or a sulfide. I'm guessing Evapo-Rust is a reducing agent, an electron donor, not an acid like naval jelly, vinegar, muriatic acid, citric acid or the other "etching"
systems commonly used. (There's a chance, I guess, that it's some sort of buffered acid. I don't think so, but I need to beg/borrow/steal some analytical time from friends to see what we can measure.)</span></div>
