Got home today from detecting and was checking a few of my finds, the usual tooth brush and baking soda under running water. The wife comes over and says why don't you try the Mr Clean Power Eraser. In case you never used one there pretty amazing how they clean.
All I can say is WOW, it cleaned a 64 rosey spotless as if it just left the mint. Doesn't work on crusty Zinclons.
Give it a try
