Artifact Conservation
Electrolysis is the standard conservation treatment for iron artifacts recovered from salt water. The idea is to drive out the chlorides (salts) that have penetrated the metal.

Comparing Rust Removal Methods
The scale gave in and broke in pieces without resistance, and "healthy" iron metal appeared underneath. By far, the Electrolysis method showed the best results. All you have to do past electrolysis (and before proceeding with conservation and preservation techniques) is to clean the freshly derusted artifacts promptly and thoroughly.

Preparations and Assembly of Electrolytic Setup
Rust Inhibitor is used for the after-electrolysis treatment of iron artifacts: it prevents subsequent rusting, and seals the iron surface against the effects of gases and moisture for a long time. Acetone is the most effective means for dehydrating the iron surfaces, and for cleaning the residues of oils, minerals, and other contaminants off ...

Line Of Sight in Electrolysis
NOTE: There is no risk of over-treating an iron artifact using electrolysis as the de-rusted iron is not affected by the process, and, therefore, the artifact may undergo the electrolytic de-rusting indefinitely as long as the current continues to flow to give it protection from corrosion.

Multiple-Artifact Electrolysis
Medium-Sized Iron Relics Are Included into Multiple-Part Electrolysis. 5) Multiple-Part Electrolysis of Medium-Sized Artifacts. When you have a few medium-sized artifacts, you can derust two or three of them at once if you use additional cathode connecting sets (see details in the "Making Connecting Sets" section on page 10).
