In plain termsplastic or glass. "Before and After" Photos of Artifacts The procedure is as follows: The prepared solution is poured into a container. Connect the positive (red) clamp from the battery charger to the part of the anode thats protruding from the water, so the red clamp remains dry. Brass is soft enough that it won't scratch iron or steel. First prepare the electrolyte liquid solution, which is made with the ingredients of washing soda and distilled water. Just keep the nonferrous metals out of the bath and it works great. The power clamps should never touch the water, or they will get corroded. 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. thanks for the instructable though, I like it! We'll assume you're ok with this, but you can opt-out if you wish. If you are't doing museum-quality conservation work, however, the higher voltages do work faster, and while you lose that small amount of material that wasn't reconverted, none of the base metal is lost, and that's what most of us are concerned about. Unlike other methods, electrolysis can clean rust in the smallest of corners and crevices. The proper way to remove rust is to do it with between 0.85 volts and 1.1 volts.

NOTE: Special attention should be given to those iron artifacts that have rusted in a salt-water environment! Electrolysis converts stubborn reddish iron rust to a black chemical compound that scrubs off quite easily. Let us know if it helps or how it works. 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. 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. These acids are naturally occurring in nuts, vegetables, and fruits, or used as an additive in medicines and foods. I use the tap water, and then just have to put more efforts into cleaning the iron piece afterwards.
