RE: Proper way to clean a mount....
take a feather duster and dust real good to remove the dust. then dampen a soft cloth with neatsfoot oil(just enough so you can tell it on the cloth) ( you do not want enough to wet the hair ) wipe with the hair lightly.
then put a drop on the nose and wipe lightly.
that should do it.
there are things that you can get from a taxidermy supply co. made just for cleaning and shining the coat of a mt.
