I love that stuff.
It works a treat, even if you use plain washing soda.

Have you tried plain washing soda with the carbon wand? Or are you
referring to the tank-type treatment?
I see what you mean. I used scrap steel as my anode
with a plain washing soda electrolyte. Ted warns against
a metal anode but I don't understand why that is inadvisable.
I haven't run into any problem other than to protect the
cleaned surface Very Quickly as it does tend to oxidize
rapidly once clean.
BTW, my "wand" is a little exotic. It's a slice of Poco 3 EDM
electrode that I cut off with my hand miter saw.g
That is almost Rocket Surgery!
A carbon electrode for use in an arc torch is a lot cheaper,
although you may have some trouble finding one that doesn't
have the copper plating. I did, which is why I sliced into my
Stirling-engine piston supply.
I have a small box of 5/16 dia. carbon arc gouging electrodes.
The copper plating would probably dissolve in an acid bath.
They would probably work a treat in this application.
