Hi D.P.,
I have had fantastic results with a product that Stanley Steemer sells called "Odor Out". It is really easy to use - just spray it on and let it dry. It is one of those products that has the live enzymes or bacteria or whatever it is that eats the organic stuff (sorry, not the best explanation - that is my vague understanding of how it works). The product is meant for fabrics and I have used it on my couch and it works great. I have also sprayed it on the hardwood floor before, but I don't let it dry because I don't know if that's a good idea or not. But if it's inside a cabinet, maybe worth a try. Good luck!
