How to get rid of smell on Aneros?

I have an Aneros Helix Syn. One day, I was feeling lazy and did not use an enema beforehand. BIG MISTAKE. When I took my toy out, it was colored in brown. I’ve washed it many times in soap and warm water and rinsed it in a vinegar/dish soap/water solution, but there’s still a smell when I hold it close to my nose. Anybody got any ideas on how to get rid of the smell?
