[Histonet] RE: Metal molds

[Goins, Tresa]

I knew I might catch some grief for not cleaning our molds for five years, but my workplace is clean and organized.

Some things just work better without being cleaned with soap and water - I have a fifteen year old cast iron skillet that is as non-stick as Teflon due to a natural patina - maybe the paraffin blocks easy release from my "un-clean molds” works for the same reason.

We clean molds every day.  My preferred method is heated water to melt the paraffin off, then allow to cool.  Peel the paraffin from the surface of the water, remove the molds from the water, then dunk them about 10 times in a mixture of alcohol and mold release.  Allow to air dry or dry in a low temp oven.


In my experience, molds that aren't cleaned on a regular basis make it very difficult to remove the embedded cassettes even if very, very cold.  It's easier for me if my workspace and tools are clean and organized.
