I have a few cleaned skulls that I am trying to degrease. I do not want to have acetone in my house as I live in a small place. Does anyone know if I put the skulls in a stainless steel pot with lid if I can place it outside in very cold temperatures (5-10 Farhenheit) and it will not freeze? Or should I just wait for warmer temps? Thnaks in advance,
Seth

But you have to get it pretty cold -139 degrees Fahrenheit or -95 degrees C. There are much safer ways to degrease your skulls than using acetone. Epo-Grip Bloodout Degreaser does a good job and is non-flammable and biodegradible making it easy to dispose of.
The acetone will not freeze at those temperatures, but will freeze at temperatures mentioned above. Warmer temperatures are better for effective degreasing.
