Posted on r/coins: How to clean grimy and rusty coins?
I had a bunch of old coins from different countries and they were stored in a rusty metal container that was also exposed to water at some point. I checked it recently and many of the coins inside are covered in rust and grime and some of them are even stuck toģether. Any recommendations for cleaning them?
