I have NO experience with the issue of smelly pearls, but am wondering if putting them in a closed environment with a separate dish of baking soda might help, as it's a great odor absorbent? Like for example, a small dish of baking soda, the pearls on a plate, and a glass dome over ... or a large container with a small dish of baking soda, the pearls next to the dish, and a lid on the container?
Thank you CathyKeshi. The smell is gone now.
