Get a container that can be sealed airtight, that is big enough for the object that needs to be deodorized.
Fill the bottom with activated charcoal and baking soda
Place the object that needs to be deodorized in the container, but on a rack or in a bowl or something so that it isn't actually touching the charcoal/baking soda mix.
Seal the container, and put it someplace warm and dry for a few days.
Lather, rinse & repeat if necessary.
