Removing caked on dirt?

[ripvanb]

What’s the best way to remove the caked on dirt from relics like buckles, buttons and small iron objects?. An Ultra sonic cleaner, Electrolysis or another method? I usually just toothpick things since I don’t like getting relics or coins wet.

Electrolysis is good for removing rust. If it’s just dirt that you are dealing with, the best method that I have found is to soak the object in distilled water. Each day use a toothpick to work at getting the dirt off a little at a time and make sure you change the water daily.
