There's a product on the market called Fabreze (or something like that) that's
supposed to eliminate odors.  You can get it in just about any supermarket.  You
just spray it on and let it dry and the odors are gone just like that.  I used
it on my '88 Wolfsburg to get rid of the wet dog odors - sprayed every inch of
the bus - and it worked quite well.  A dog ain't a mouse, so YMMV...
