I've got a few skulls that are cleaned and ready for degreasing. I've grown very weary of the dawn method, patience is not my virtue and neither is a half ass job, hence the conflict. Think I will give acetone a try.

As a side note, my deer skulls soak for months in dawn to get them museum quality. There was one that took eight months, and that was with heated water. The references I see to a few days to a few weeks have me perplexed. Here is a quote from a taxidermist that was posted in taxidermy.net forum, so I'm not the lone ranger.

I have used the dawn and 120 deg water method using a tub and hot water tank element for a while now, but it seems to be quite costly on the power bill being that it takes months to degrease. Id like to try using acetone or ammonia but not sure how to go about it with antlered skulls


Here's a link with good info.
