Let us know if it helps or how it works. Many professionals claim that washing soda is more useful for electrolytic cleaning than baking soda because the washing soda is routinely used to remove oil, grease, and certain minerals. Also its a good idea to do this experiment outside because hydrogen and chlorine gas is produced and hydrogen can ignite very easily and chlorine is very toxic but i did mine inside because mine was not producing that much chlorine in the process and if you don't want to have the problem with chlorine gas, then instead of using salt as your electrolyte, just use Washing Soda as your electrolyte.And do not use stainless steel tools as it has a poisonous substance it produces. Leah demonstrates how to completely remove rust from a pair of severely damaged pliers using the process of electrolysis. One question, what do you do with the water afterwards? The concept behind this is a Faraday cage/RFID blocking for cards ect. I'm not having much luck with vinegar and steel wool. Always work in a properly ventilated area. The ions react with the electrodes, either receiving (reduction reaction) or giving up (oxidation reaction) electrons. I could easily see a 10 gallon fish tank and battery charger for cleaning up some vintage tools. In addition, chlorides (they enhance rusting) and other anions are drawn from the iron surface and migrate toward the positively charged anode by electrolytic attraction. Thanks for the write up! Are there tables of wastage rates for different fruit and veg? The procedure is as follows: The prepared solution is poured into a container. Just google salt-water electrolysis products if you don't believe. You can further suppress the issue by adding only vinegar (acetic acid). MathJax reference.
