Put together an electrolysis tank for restoring cast iron pans! Removes carbon buildup, old seasoning, and rust.
Running it off of my adjustable power supply, running at 12 volts, pulling about 5 amps.
Electrolyte is sodium carbonate (washing soda, annoying to find), and my sacrificial anode is an old steel baking tray.
Trying it out with a small skillet first as a test, but working well. After less than half an hour, a lot of the carbon buildup is gone already.
Should take about an hour and a half per pan.
