Salt water in coastal regions or from winter road salt, as well as acid rain in some urban or industrial areas, are known contributors that speed up oxidation. This works only for metals with Iron composition which are known as Ferrous Metals. I was restoring an older cuckoo clock and found that the battery had been left in, and severely corroded the battery tabs. However, there is no such risk with electrolysis. These industrial rust removal products are also offered in a gel form. Only now you are dissolving either washing soda (or "soda ash") or baking soda (also "bread soda" and "cooking soda") in water. Introduction to Electrolysis of Iron If it was not for the by-products and contaminants - any substances besides baking or washing soda, that get into the electrolyte from water, anodes, cathodes, and iron objects, and then gradually build up a huge disgusting mess in the container, one could use the electrolyte forever. You should not use salt (sodium chloride) as an electrolyte. Can you use it again for other rusty things? Fill your desired container with water and add salt( the more salt the faster the process and a saturated solution will work best. During this period, the anode will slowly transfer its molecules to the other object, and will gradually lose shape or become coated with rust. Unfortunately, these parts are generally oxidized, so I've been assembling an electrolysis tank for it. You also have the option to opt-out of these cookies. One just would have to refill the container with water which is converted into oxygen and hydrogen gases during the process.
