For rust removal this is correct.

Anything that makes the water conductive does work to some degree but may not be optimal for the Electro Chemistry involved.

Best for Ferrous is sodium hydroxide and second is sodium carbonate (washing soda), third is sodium bicarbonate (baking soda) last is sodium chloride (common table salt). These also change the pH of the solution which effects the chemistry.

There is a STICKY at the TOP of this sub-forum with a link to a paper detailing the process. Good read to understand what the electroysis is doing and why.
