Usually a lukewarm bath solves all smell problems. What I did for mine when I fed it live (and the mouse pissed all over my python) is put her in a tub with about 2" of sphagnum moss and 1" of warm water. The wet moss absorbed the water really well and after letting her soak for 40 minutes, the smell was completely gone and she smelled like sphagnum moss
Then, throw away moss (or flush down the toilet), and presto.
