What voltage will electrolysis remove rust?

Voltage: The process of electrolytic removal of rust works best with 24 volts DC supplied by a car battery charger. Voltages above 24 volts DO NOT really offer any greater efficiency, and generally cause the energy to get wasted as heat off the electric wires and in the electrolytic solution.

Does electrolysis rust removal weaken metal?

The rust is “reduced”. This reduced iron will form a somewhat porous layer of new iron on the metal object being cleaned. After electrolysis the iron object will rust very quickly unless it is protected because this porous layer of new iron has a high surface area.
