Using electrolysis to remove rust

[bandersen]

I was inspired by PredictaNoob to try electrolysis rust removal on an Admiral HV cover.

Here's the rusty, painted cover.


First, I removed the paint using Citri-Strip. Then, mixed up a bucket of electrolyte. I'm using Arm & Hammer washing powder (Sodium Carbonate) and about an amp of current. The positive lead is connected to a sacrificial cold chisel. The negative lead is clipped to the cover.


I let it run overnight and it worked out very well


Finally, a little black satin enamel paint.


It's a messy slow process, but it does work well. I think I'll stick with Naval Jelly for small parts and smaller patches of rust and use this technique for really rusty parts that are easily submersible.
