Believe it or not but I successfully removed a rather large calcium carbonate
deposit on an Odessa with a dental probe and WD 40 (I love WD 40). It wasn't
easy but I was careful not to disturb the finish and it looks great. If you
take this approach, expect to wear down and constantly refresh the point on
the dental pick. I use a dremel mototool for this pupose.
