Na facebooku mam "polubionych" parę stron o monetach antycznych.
Seul Roll napisał o monecie która skutecznie czyścił:
I won the uncleaned coin lottery with this Caracalla. I'm sorry to say that this does not happen too often. I had to post it with the intermediate cleaning stage, otherwise it'll be hard to believe that this is indeed the coin hiding under that crust.
UPDATE to this post: To answer all the pm's and questions I've been asked here, I'll be posting a link my coin cleaning manual tomorrow, which I finally finished writing. String attached: none, really. It's free, but it's on my page where I offer my newly posted "Coin cleaning kit." But you don't have to buy the kit!
