Sea sponges have long been used for bathing and scrubbing. The ancient Greeks even used them for this purpose. With the modern preference for more natural products, sea sponges are popular once again. Sea sponges naturally accumulate less bacteria and mold than synthetic ones, but as they do last a long time, you will probably want to clean/sterilize them at some point. As they are so resistant to problems with bacteria, you can now even buy reusable, environmentally friendly tampons made with sea sponge material. In fact, coastal dwelling women have used sea sponges in this way for centuries. Sea sponges are hypoallergenic and, as they are a natural product, are fully biodegradable.

Cleaning Your Sea Sponge for Ordinary Use
Wash your sea sponge using antibacterial soap. Although it is resistant to bacteria, it can't combat it completely without a little help occasionally.
Soak your sea sponge in a mild bleach solution if you feel it needs a good clean and you have had it for a long time.
Dry your sea sponge in the sun if you can. If you keep your sea sponge dry when you are not using it, it will last longer. If you dry it in the sun, the ultraviolet rays will also help keep bacteria from growing on the surface.
Sterilizing Your Sea Sponge Tampon
Rinse your sea sponge tampons between uses during your period.
Put the sea sponge tampon in boiling water for 60 seconds or let it soak in a colloidal silver solution to disinfect it.
Mix a solution of baking soda and cider vinegar with a few drops of tea tree oil. Place cooled disinfected tampons in mixture to soak.
