Removing decarb with DC?

[Raymond Richard]

I've read that it works real well for removing rust. All you need is a battery charger, a non metalic container with baking soda and water, and a piece of stainless steel. You clip the stainless on the positive and the work on the negative and in a few hours with a few wire brushings in between its suppossed to do the rest. I'd give it a try if I still had my battery charger. Somebody try it and let me know if it works for removing decarb. Mixing ration is 1 table spoon soda to a gallon of water and yes I know about soaking in vinegar to remove decarb. Just thinking this might work better. Also read it works better if you keep the two pieces as close as possible without touching.

Yes, Ray, it does work for rust.
i was taking some rust off a double shear steel plane blade, and kinda forgot it was still on when i ate dinner, then a few hours late, it was really pitted...
No rust, but serious pitting... scrap that one...

Decarburization is a layer of lower carbon content than the rest of the steel.Scale is iron oxide. Scale can be removed mechanically [grinding] and chemically also[ acid]. Decarb is removed mechanically.

I see said the blind man works like a charm for rust, plus if you are easily amused like me you get to watch a swirling bucket of bubbles!
