For washing soda I use 1tbsp per gallon, any more is a waste (won't help the process), to help it along I use several electrodes to collect the rust, paint, etc that comes off the part I'm cleaning. Tannic acid, oxalic acid, citric acid, and Ethylenediaminetetraacetic acid (EDTA), can all be used as an industrial rust remover. Also, in my experience, the voltage is key for electrolysis (FYI to commenters). During the electrolytic derusting, two processes are happening simultaneously: 1) much of the red rust is converted to Fe3O4 and becomes detached from the iron object's surface, 2) the remaining rust is converted into an easily removed deposit. These are mineral acids, and they are highly corrosive, especially in concentrated forms. 3. Since the chemical process differs from mineral acids, oxalic acid and other weak acids lower the risk of metal flash rusting, however, it is still a risk. 0 ratings 0% found this document useful (0 votes) 3 views.
