    Electrolytic rust removal is very effective, basically this works the same as electroplating items with silver, nickel or chromium, just your removing the oxide layers instead of plating another metal on the surface. But as the video unstated, be very carefully about the levels of hydrogen give off during the process, as these are quite high, and so if possible do this outside. The process also works very well on high chrome and nickel content steels, as I've a few friends that use this process for antique sewing machine restoration. Personally though I'm a big fan of sand blasting, and on most items this is not a problem.

    Wow thats all I can say, it just goes to show how much the surface oxidised metal hides the real condtion of the artfact. Quite frankly going by the first picture you would think that this mortor bomb would have lost any detail or just be one solid lump of rust.

    Seems that the cast iron body is more resistant to rust than the sheet metal fins. The majority of fins blown off mortar shells that i've found were rusted beyond repair and left in place....
    The only thing that this shell needs now is a coat of protective oil and a nice spot on a shelf.

    Hey Nige,
    I am very curious to see some of those restaured sewing machines; is there a possibility to get in touch with your friends?
