Cooking your specimans in Biz or Axion laundry detergent may be a better way to clean a skull and may give you a much higher quality of bone or skull in your collection. Biz or Axion laundry detergent both contain enzymes that rapidly break down proteins and accompanied with the bleach in these products, you will get a real fine finished product.

Naturally, you must remove all the skin first, just like with the Dermestid beetles. A crock pot works fine for smaller specimens as long as you can control the temperature, which should be kept at about 68 degrees Celsius. Anything above 70 degrees Celsius will denature the enzymes. After about one day, conduct a preliminary cleaning with a tooth brush and complete the job on the second day.
