You can electrostrip chrome with muriatic acid.


That's interesting. Have you done it? If so, what are the basic
requirements (acid strength, voltage, current, polarity, any special
requirement for the other pole)? How fast is it?


I haven't done it; my reference is Caswell's Plating Manual. 2
parts acid to 1 part water. Polarity would be workpiece positive.
Cathode (other pole) might be chrome, stainless or carbon. Voltage
would be fairly low, maybe 3 volts or so. Strip rate would vary with
current. Chrome plating takes a lot of current -- an amp per sq in
or so -- stripping might be similar.

Caswell also offers an alkaline chrome stripper that requires current.
I haven't tried that either. The advantage to the alkaline stripper
is that it doesn't attack underlying nickel.
