DanielGu New Member Portugal 22 Posts	Posted 06/11/2018 12:21 pm I wanted to know your take on coin cleaning, some say no, others say yes... Ancient coins: I think its best if they are just soaked in destiled water and cleaned with a toothpick and/or with soft brush (only to remove the bigger chunks of clay) Medievel coins: (i have no idea whatsoever) *modern coins: I clean them with a 1 week bath in Olive oil, then distiled water bath, then a litle bit of soap and a soft brush (might try electrolysis or baking soda) Give me your honest opinions, I have received a ton of silver and copper coins all full of oxidation, and the silver ones with black spots, I dont know what to do since there are such diferent opinions (can I clean them with baking soda?) Also I have some roman coins covered in clay (should I buy proper tools or a toothpick does the trick? Thanks,Daniel Edited by DanielGu 06/11/2018 12:24 pm Report this Post to the Staff

Acetone and distilled water seem to be the only two acceptable solutions used here on CCF to improve a modern dirty coin. Spots in the metal are usually always there to stay.

jskirwin Pillar of the Community United States 616 Posts	Posted 06/11/2018 7:54 pm I sold off my modern collection last year after being away from the hobby for decades and I was pretty surprised how things had changed. I grew up in the 1970s when cleaning was common. Judging by the slabs labeled "cleaned" it appears that an entire generation of collectors ruined their collections back then.
