Does anyone know anything about Electrolysis rust removal. I tried it today on an old drill bit as an experiment and it worked quite well but I was wondering how I could improve my system. I was wondering how the voltage, amperage and surface area of the anode affect the time taken and the quality of the part. Also is there anything else that Effects ( or Affects ) either of these these. I used 2 litres of water and 2 table spoons of soda crystals with a 5 volt 16 amp supply. When I perfect my method I will clean up a very old and rusty Lister D.
