I was all hot to get it done fast, but the picking at tissue got old quick. I moved on to a two hour simmer with the antlers wrapped with foil, trying to keep the water around 170 degrees or so. The flesh was still really stubborn coming off and I got lazy, so I put it out in the garden with a tote over it (to keep the rodents off it). The cold weather in December slows down the decay rate significantly, and the bugs I was hoping would clean it up were only about 10% of what I was hoping for.
After about six weeks, I could see that the skull was starting to discolor, so I pulled out the pressure washer (like I should have done six weeks before) and using low spray pressure, cleaned it up in about 20 - 30 minutes. Two weeks drying in the garage and it moved to my office where it sat again.....
