[Histonet] contamination/molds

[Sue Barnes]

We place the molds on the embedding chamber lid until they warm, so that the moisture doesn't get in the xylene,  We place them in a container of xylene for the day,  In the afternoon we place the molds in a basin of Dawn dish liquid and hot water, this displaces the xylene.  Rinse the molds in clear water and leave on the counter to dry.
It has worked for years.
