It's sold as a laundry booster, and can be found near laundry detergents in stores. In order to answer the question we also need how large a part you are electrolyzing. These derusted objects showed no pitting, in contrast to the formerly badly rusted artifacts which showed significant pitting where the rust had removed iron bit by bit over time. Lye (sodium hydroxide) is a powerful base and is very harmful: it will immediately damage the skin on contact, so appropriate protection must be used. When table salt (sodium chloride - NaCl) is placed in water, the salt (a solid) dissolves into its component ions, according to the dissociation reaction: NaCl(solid) Na+(aqueous) + Cl(aqueous). All that is true; however, the washing soda is a skin irritant. I use washing soda instead of salt, works really well. This is a fantastic way to remove rust and oxidation from steel and iron. DirtyYogurt I might be crazy here, but I was under the impression that cast iron didn't have a non-stick surface. Because the natural process of rusting is an electrochemical spontaneous reaction, during the electrolytic derusting, this reaction is put in reverse. Gas tanks of the teens through the 1950's and even later can have a number of chambers created with the inclusion of baffles. Uploaded by Vctor M Gonzlez. Multiple-Relic Electrolysis 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. Industrial rust removers using weak acids are typically found in bath or gel formulations. Weak acidslike oxalic acidcan be hazardous in a highly concentrated form, but they are naturally-occurring and carbon-based, so they are less toxic and less corrosive than mineral acids. To the water add baking soda. Electrolysis was discovered by English scientists William Nicholson and Sir Anthony Carlisle, and independently by a German chemist Johann Ritter - they all decomposed water into hydrogen and oxygen, in 1800.

Any spills on the skin or eyes should be washed immediately, and medical treatment should be administered if necessary. Today electrolysis is used for many purposes, including the production of chlorine, hydrogen, and sodium hydroxide (caustic soda), the extraction of metals from ores (aluminum, copper, zinc and lead is produced industrially in electrolytic cells), the coating of materials with thin layers of metal (electroplating), the implementation of a number of electrochemical analytical techniques, such as polarography (the study of solutions or of electrode processes), and, of course, the cleaning of archaeological artifacts. Understanding what causes rust can help to understand how to get rid of it, and which methods work better than others, and why. Since weak acids occur naturally in the environment, they are far less toxic than the mineral acids listed above. When an iron object is exposed to the air with some humidity, it undergoes a process known as Rusting - an electrochemical process. The electrolyte (described in the source) is based on water and sodium carbonate. the cause of a rust issue, 1551 N. Burkhart Rd. Look at the active ingredients as well as the recommended safety and disposal precautions to see whether the product uses strong acids, weak acids, or an acid-free, water-based formulation. In case you wish to use the washing soda and are too lazy to go to the supermarket or drugstore to get it, you can use baking soda to make the washing soda at home. Another advantage that electrolysis has over brushing, grinding, or other conventional rust-removal methods, is that none of the original iron or steel gets removed, and the process is usually not caustic or noisy, besides being comparatively inexpensive.
