Potassium metal

Potassium metal: Are we allowed to demonstrate potassium metal in schools? How do I deal with it if it has oxidised?

I have just noticed that some of our potassium metal in light paraffin oil has some white fluffy/crusty bits on some of the larger pieces. A Lab manual suggests that the metal has been oxidised and the crusty bits should be removed.
