We boil them in soapy water every day.  After boiling let them cool and the paraffin and junk floats to the surface and solidifies.  Remove the paraffin and rinse in running water.  Dry in the oven.  After the dry step you can spray mold release agents or use them without.

For those labs using the metal embedding molds,  how often do you clean
them with xylene and alcohol?
