    Detailed PDF Coin Cleaning Guide and Galvanic Wrap Method

    Here is a free PDF cleaning guide that has many of the techniques I use.
    http://nobleromancoins.com/down.php?...ning.coins.pdf
    It is published by a reputable coin dealer I have purchased coins from many times.

    I also use the Galvanic Wrap Method:
    Mix up a 5% solution of Sodium Carbonate (5 grams of sodium carbonate in 100ml of
    deionized water) and you wrap the coin in a double layer pocket of
    aluminum foil, add some of the solution inside the wrapping and then
    submerge this into a container with the rest of the solution. Let this
    set for about 3 days then check the progress. The aluminum foil will
    deteriorate since it is acting as your sacrificial anode in the
    process. You can continue this process indefinitely until the coin is
    clean since it is a very mild technique.

    I have had success with this method on many coins, but others sometimes still
    needed electrolysis cleaning even after this process.

    Measurements:
    5 grams (1 heaping teaspoon)
    100ml = Half cup or about 3.5 Fluid Ounces


    Method Source:
    The Archaeologist's Manual for Conservation A Guide to Non-Toxic,
    Minimal Intervention Artifact Stabilization
    Rodgers, Bradley A.
    2004, 220 p., Soft cover
    ISBN: 0-306-48467-6

    I am also successfully using the Air Abrasion Method with sodium carbonate as the blast media and a mini sandblaster.

    I hope others find this information useful.
    I will try to answer any questions to the best of my ability.

    Thanks for the post. The PDF link is really quite incredible. A great read. Got up to pg. 120 of 286! Very easy to read & click through. Love the clear presentation style!

    Update: Note he does not use plug in tools, just battery powered & warns of plug in tools.

    Re: Detailed PDF Coin Cleaning Guide and Galvanic Wrap Method



    please do not use machines Dremel (or any other brand) with ancient coins .... IS THE WORST YOU CAN DO TO A COIN! from experience these machines destroy the coins, because they are unable to remove the oxides and leveled the reliefs above, the result is a coin worn and without the minimum relief that could see with other methods.
    I speak from experience.
      No matter how long the storm, the sun always shines again between the clouds ......
