You're not moving the rust, you're actually moving the oxygen (oxygen bonded to iron = rust.. electrolysis forces hydrogen gas to bond to the oxygen, creating H20. The voltage is hard to gauge. Because the electrolytic rust removal generates hydrogen gas, one has to make sure the hydrogen gas and its mixture with oxygen - another by-product of electrolysis, do not accumulate to reach an explosive concentration. Doing it the wrong way would not make a happy valentine's day gift. What about different types of tools because other tools might be harder to wash with steel wool and i'm going to relate to that with a drill bit and a pair of pliers.
