Try letting the clay dry out real good, then wetting it for a day, and get your self a "Mystic Cleaning Gun" from the American Nigara Corp.
The spray can be adjusted from a fine pinpoint spray that will sting your fingers real bad to a gentle wide mist that wouldn't hurt your eyeball.
You'll find a few posts here in mindat about using them. Just use water in it, it will even clean in the deep cracks.
Cleaning with a razor, dental picks or other such things will only damadge and scratch your specimen's.
Another thing that sometimes works is denture cleaning tablets, if the clay isn't too hard.

I got good results by using Dithionite in a bufferen solution. The clay is stabilised by the iron ions. The dithionite solves the iron in the clay and makes the clay soft and friable. After that you can remove it by an old tooth brush.
However, as Rock Currier said: There are different kinds of clay.
