There is a product called "One Drop", which is fantastic for taking
care of odors of all kinds.  You just put a drop on a saucer and place
it inside the article, close it up and let it go.  For really obnoxious
stuff, sometimes it takes a couple of applications, but it is great.
We have used it both on musical instruments and around houses.  It
does a great job.  Usually it is found in super markets either in the
cleaning section or in the pet section.
