I love learning new things. I have lots of badly rusted parts which need to be refurbished for Project Phoenix and so I searched the internet for ideas and stumbled across “electrolytic rust removal” and thought I would try it. Brilliant. This is incredibly effective and involves no harmful materials. Here are some before and after pics. After treatment these parts were simply washed in water with a bristle brush and then given a light wet rub with Scotchbrite.
