I am in the process of mounting the fan myself. I was told by a hobbist taxidermist to clean out all the meat you can out of the fan but be careful not to mess up the skin holding the smaller feathers in front of the fan. He said after that pour some borex (detergent) on them to dry out and keeps bugs out. Is this a good recommendation? Is there anythink I should do to the beard to perserve.
