[QUOTE="CygnusCC, post: 24497154, member: 120299"]I received this Argentinean Dos Centavos as part of a random world coin set and saw that it had some pretty significant verdigris. I thought this would be a prime opportunity to experiment a bit. The original coin was this: [ATTACH=full]1552776[/ATTACH] I sent it through a few cycles of my ultrasonic cleaner with distilled water and a small drop of dish washing liquid. My cleaner only runs in 2 minute intervals, so probably 30 minutes total. Lots of restarts between 5 minute cool downs - it's a cheap model cleaner. After a final distilled water rinse: [ATTACH=full]1552777[/ATTACH] Then I applied the Verdi-care. I started around the denticles since that appeared to be the majority, but then lightly spread it to the motto with a q-tip. Then I got impatient and applied it to the whole coin. I finished with an acetone soak/wash at the end, but I'm not sure that was needed. I was just looking at the scary 'if this touches your skin' warnings and wanted to sluice the thing down. :) [ATTACH=full]1552778[/ATTACH] I was never able to completely remove the verdigris above the D in libertad, but all in all I'm pretty happy with the final result. Sorry for the color differences, my USB camera doesn't retain the settings between runs so I had to eyeball it.[/QUOTE]
