Making Hydrogen .... electrolytic rust removal

10 gallon bucket with two sacrificial anodes

add 10 gallons of water mixed with 1/2 cup of washing soda and connect the battery charger, positive on the anode, and negative on the item we want to de-rust. 12 volts is good, 18 volts must be better and watch the bubbles go..... make sure you do it outside unless you want to recreate the Hindemburg accident in your garage.
after 3 days it looks like this
dry and passivate immediately with phosphoric acid or it will start to rust right away
and the final results
