Thought electrolysis was using DC to make a chem reaction. Like running DC through H20 to produce Hydrogen and Oxygen.
I remember trying to make one of those H20 cars with electrolysis, didn't work so well.
That's one way to make it happen.
The other way is slowly over time, plumbers and Hvac guy's see it also when copper and black iron pipes are joined.
It makes them corrode.
But this takes years
