Well, I let it boil for a few hours, and the concentration of CA was obviously enough, as there was just enough room to sink two nekkids up to their necks in solution and a tablespoon(ish) of CA, and I kept up with replenishing the water in both the solution and the pot of water that the whole mess sat in.
The results? Now the brass parts are a bit pinkish, and the chrome parts are completely devoid of any calcification or lime.
Other than that; nix, nyet, nada. No flaking, no peeling, no nothing.
Thanks for the suggestions, though?

Now you just have to buff and they will be as shiny as gold.

Y'know, except all the parts with all the chrome all over them still...

Well obviously there is either a difference in the plating itself, or in the thickness you need to remove. Or there is a last option, you used a different type of pan that did not have a place for the chrome to deposit to, so it stayed where it was.
Have you considered placing a piece of sacrificial metal in there with the PF's to give the chrome a place to deposit?

Uhm, that'd work with an electro-stripping version of the removal process, but the 'citric acid stripped the chrome off the inside of my boiler' stories had no anode or cathode to electro-chemically remove the plating, and reported it flaking off. As I read that, the adhesion (molecular, chemical, whatever) between the two surfaces gave up, not that molecules of the chrome were transferred onto another surface.CRCasey wrote: Or there is a last option, you used a different type of pan that did not have a place for the chrome to deposit to, so it stayed where it was.

All I know is that there were no (none, zilch, zip, nada, nyet) chrome bits anywhere but still where they were when the process started.
