Rare coins of course are not to be cleaned at least not by a lay person. But I'm thinking TSP or tri sodium phosphate. And you could leave a bucket somewhere and keep using it.

Simple, pour some vinegar into a small bowl, place a few coins into the fluid and shake the bowl back and forth until the coins shine!

It was a shock to me honestly. I know three customers for the souscription series and had seen renderings and link low-resolution photos of the watch and they all left me relatively link cold despite at least one telling me this link was a GPHG winner in the making. But trusting my friends' tastes I took the meeting anyway and handling the watch was like being struck by lightning.
