Electrolytic Derusting ==> first attempt

UpUp


My first attempt. An old, very rusty railroad tie plate. I use my welding machine for derusting. I set current to about 17 amps. The plate was negative.

I only derusted a part of the plate, to make effects more comparable. I then washed it with a scrubbing pad. Then I wirebrushed a part of what was derusted, so that you can see how the surface looks without wirebrushing vs. with wirebrushing.

A little guideto the last picture: left side -- rust, middle -- derusted and wirebrushed, right -- derusted but not wirebrushed.
