Thanks for that Steve. A couple of points you might clarify if you would. First, you use the Lectric Washing Soda as electrolyte in a water bath, for electrolytic cleaning? Second, you use a standard battery charger as the source of electrical polarisation? What kind of battery charger - voltage, current rating, electrical design? What polarity for the part being derusted - positive or negative terminal of charger? How long do you run it for? How do you decide when to stop? Do you remove paint/wire brush the part before electrolysis?
