20 gallons x $18 a gallon = quite a lot of concentrated potato juice (look up oxalic acid)
Just be careful not to put things with black oxide in it (it will remove it).
Dilluted 'wood bleach' also works but handle that stuff with care (unlike EvapoRust it is much more caustic).

Also you might consider sand blasting or using an 'air eraser' on it.

Planning on powder coating it?

It is indeed expensive, though there are ways of maximizing it's utility. I have used it successfully by soaking a rag or towel with it and draping that over a part. At the end, just squeeze as much as you can back into a container. It helps to have the edges of the rag/towel submerged in fresh evaporust.

You can also use vinegar, or sodium carbonate and a power supply. Did a whole lathe that way.

Sand blaster makes quick work on things like that heh.

I have to agree a good bead blaster is all a iron clad robot needs.
