Hand wash with woolite and hang dry. preferably outside
Wool, Good Wool - clothing shouldn't really hold much smell.
At least that's been my experience.
This is one of the better properties of wool amoung other things.
It probably just smells like a stinky sheep. Maybe the coyotes will smell it and come running for dinner!
Remember that if you wash wool, hang it and periodically pull to stretch it.
That will keep it from shrinking a size.
