Electropolishing and 3D printers

I am looking for better ways to clean growth lines from printed
parts.

I’ve read about electropolishing / electrostripping gold to remove
the top surface, but haven’t found much on how to do it.
I know it used to be done with a cyanide solution, but that there
were newer less dangerous methods.

Will it work for what I’m trying to do? Could anyone point me in the
right direction?

I don’t know if it will work, but I have thought of dipping it in hot
wax to coat it. Will take some hand cleaning. But hey…

Cheers,
Chris Lund
