To clean my molds I periodically put them in water with soap and bring it to a boil. Then I set the pan somewhere to cool and once the paraffin hardens I take it off then rinse the molds with a lot of water, dry and spray with mold release. I don't need to do this too often but I like doing it in the winter so I can set the hot pan outside to cool Roberta Horner HTL/HT Penn State University Animal Diagnostic Lab

I am in a research area where all tissue received is fixed, processed, and embedded as a general rule but we occasionally have blocks that require re-embedding. Today I was re-embedding very old blocks today and some of my pans have a brown sludge in the bottom of them that is probably degraded paraffin as the blocks were from 1970-1980 roughly. We don't normally have a way to clean our pans but this is something that is not going to just melt out and wipe up ( Very Sticky). Does anyone have any suggestion for cleaning? Thanks!
