6) Cleaning the chuck:

Soak the chuck in ethyl alcohol or a special cleaning liquid for tools. Clean the slits and the hole of the chuck with a dry scrubber or brush. 

Rinse the chuck very well, and make sure you let it dry well afterwards.  Cover your index finger with a very little amount (just a drop) of oil and rub in between your thumb and index finger. Now dab off the oil til your finger is only covered with a very thin film of oil. Now move the chuck in between your thumb and pointer.

There should be only a very thin film of oil left on the chuck.  Please act according to the saying: Less is more!
