Thanks. I've bookmarked that old link to read. Note that I posted: "..Then you'll need to remove the Coin Care."
I have developed a new process. In 2-3 weeks my profile picture will have a new look and will post to the Coin Community Forum. my latest challenge? Any idea what that white material is on the Wiener Archeitectural Medal? I collected copper my whole life. Had some recent breakthroughs with all this locked-up Covid situation so had the time to refine my conservation/soil removing process. [edited]
See my post under the Main Forum under Coin Community Forum on the outcome of this piece. CUrrently experimenting with water and hydrogen peroxide on its effects on copper. Shows promise on removing green verdigris but leaves black areas of its presence however no real effect on mint state fields or cartwheel effects so IMO more (+'s) then minuses. JPL
