I bought a pack of vanilla beans a few months ago and tucked them in a ceramic canister on my counter. They were in there a week before I remembered to package them better and put them in the freezer. Ever since then, I cannot get the vanilla smell out of the soft plastic gasket that makes the canister airtight.

The odor came out of the canister after I ran it through the dishwasher but not the plastic gasket. I've removed the gasket and have it sitting in a container of baking soda, but it's not working.

Unfortunately, this particular smell is not very pleasant. I'm not sure why, as I LOVE vanilla and enjoy using real beans.

Is there anything else I should try? Thanks!
