<p>[QUOTE="red_spork, post: 2785318, member: 74282"]I did not use sodium carbonate but a similar method for this one. I used a solution of nearly boiling lemon juice, salt and several layers of aluminum foil on the bottom of a small glass container to clean this one. It works very fast. I soaked for probably about 5 minutes total, flipping a few times and scrubbing very lightly with a soft bristled toothbrush each time I flipped the coin. I also did a full rinse with distilled water and baking soda, then another rinse with just DW afterwards.</p><p>[ATTACH=full]645451[/ATTACH] </p><p>[ATTACH=full]645452[/ATTACH] </p><p><br /></p><p>This coin was largely covered in iron oxide and the areas that show toning here were the ones that were covered the worst when I started.
