I occasionally pick up the small cast iron pots that have often been used for melting lead in so I have a small electro tank(5 gallon bucket) with a piece of stainless plate bent to fit half way around the inside of it, Well I found this really neat little cast iron pot and I went to put it in the electro tank and I noticed I had an algae bloom so I figured I would just throw some swimming pool algaecide in it to clean it up, This setup is only for items that I will not use for food purposes so what could it hurt...right...well the algaecide cleared the algae bolom right up so I put the small pot in and hooked up the electrodes, I let it run for 2 hours and then checked to see how it was doing...well the pot had a copper sheen to it and I remembered we had switched algaecides a few years back to a copper based algaecide...so out of the electro and scrubbing and wire brushing and steel scrubby pads and a few hours later I had the copper coating off my little cast iron pot, Luckily it was only on the inside but boy was I surprised when I saw that copper color, Now my question is why does the electro setup remove the rust yet the copper flowed to the iron?
Anyway...i dumped that solution and scrubbed and cleaned my little tank and set it back up and the little pot is back in a proper electro bath.
Yes...I feel really dumb :-[
