It's turning fall and then winter soon, and I simply can't just use my old maceration procedure (filling a bucket full of water, putting the bones in and letting them clean themselves in the heat)... plus, it smells too much. This skull does not have meat on it! This tutorial is used for cleaning the meat off of bones as well as degreasing them. To get the meat off, just follow this tutorial (minus the soap I guess), as it will work just the same.

Anyways, here is my setup.
1. Bones in Ziploc bags. The top part of the skull and all loose teeth are in a large freezerbag, the bottom jaw is in a smaller sandwich Ziploc.
2. A pool thermometer. It says the water is around 70*F, but that is because I had turned the heater off to clean it***.
3. Aquarium heater. This is a 50W Aqueon submersible heater that goes up to 88*F. Your heater should be set around 80*F, lower might set the grease into the bone, and that's not what we want.
4. Palmolive bleach alternative dish soap is in the bags, to clean/degrease the bones as well as whiten them a bit.
5. I believe this bucket is a 15Gal or a 10Gal, I can't remember. Get a heater that will heat up your bucket thoroughly, use more than one if necessary.

Steps.
1. Fill your bucket full of water. You can use cold water but it will just take longer for the heater to heat it up to the desired temperature.
2. Put your aquarium heater and let the bucket heat up. Remember to check your heater often to make sure it is working properly.
3. Fill up Ziploc bags with water and soap if you're just degreasing the bones. Mix the soap up a bit.
4. Put the bones in the Ziploc bags.
5. Go do something else for a couple days. Check on your bones and thermometer often, changing the water/soap in the bags as it gets cloudy.


****I had to clean it because it was getting a crusty buildup. If you see this yellowy/white crust on your heater, DON'T PANIC. It's simply limescale. All you have to do to get it off is turn off your heater (following the instructions.. some heaters like mine require you wait 15 minutes after unplugging it before removing it from the water) and then let it soak in plain old vinegar for a bit and then scrape it off.

Happy cleaning! ;)
