a little electrolysis goes a long way - cast iron like new again

14v and 2-3 amps - found some better sacrificial metal and that helped speed things up. solution is water and a bit of washing soda/sodium carbonate.

woah, that's neat. What kinds of solution and voltage are you working with here?

oh interesting, didn't know that's what that was for! sick process. what else you gonna de-rust?

yeah, plus a bunch gets attached to the "sacrificial metal" (on the right, attached to the positive terminal)

damn is that all the rust “slag” surfacing in the first pic?

plus you get a healthy, mineral rich soup for free
