""Just like new.
Just remember if you leave that alligator clip connection submersed it will dissolve too. Did you get much pitting from the bath? I have read that much above 2 amps and it will work faster but can cause deep pitting.":"

I have being do this for about 25 years with the same alligator clips and at 8mps
PITTING ??? it does not eat the metal you wont get pitting
All it does is form Hydrogen bubbles on the GOOD steel and everything outside that is pushed of by the bubbles

I would like to know where you read this:-
I have read that much above 2 amps and it will work faster but can cause deep pitting.

Where you will get pitting if have the current going the wrong way
