Is it possible to remove carbon(ized gunk) from copper by electrolysis?

Factual Questions
1

Just thinking about something I only know in the abstract–separation of chemical elements by zapping them with electricity.

I have pure copper pans unattended-to for a few years. Cleaning mixtures of abrasive and chemical nature, homemade and commercial, abound; at the stage I’m at, it’s Easy-Off doses and then step downs to ketchup, flour, and vinegar.

But the problem seems easily identified in physical chemistry. Even if I needed to construct an industrial facility to get the results, what is entailed?

Note: The pots and pans are lined with tin on the non-carbonized (inner) side. Optimally, the procedure would leave that alone, or at least not alter its other physical (and “physiological” (non-toxic in normal usage) properties as well. For a price, copper pans are easily re-tinned, however.

The handles are cast iron. That’s the complete rundown.

I think electrolytic cleaning is likely to leave the copper dull and pitted. Same for any acidic cleaning methods, including home remedy types like cola, ketchup, etc.

I would try a non abrasive metal polish and a drill powered felt buffing wheel., or if you’re going to take them to an industrial workshop, a floorstanding buffer.

Are you sure they’re solid copper, not plated? does a magnet stick to them?

Here’s a video about it. And this kind of process claims to just add a metal plate instead of using wires. I have no experience with either of those methods.

Electrolysis doesn’t do the job.

The stain removers (brasso, CLR, Metal Brite) are mild acids that attack the hydroxide/oxide hydrate layer… and prevent it reforming instantly you clean it away mechanically… The polish contains grit to help remove the black stuff mechanically.
