Why use natural sponges? A sea wool sponge taken care of properly can last as long as 10 years and a high quality silk sponge as long as 4 years. Synthetic sponges will only last a week or so until they start falling apart and get all nasty with mildew and bacteria. Natural sea sponges actually have enzymes in them that inhibit the growth of mold, mildew, and bacteria.
Another great reason for choosing natural sea sponges instead of synthetics sponges is that there are no harmful chemicals in natural sea sponges. It is all natural and safe to use on all skin, young, old, sensitive, rough, and also safe to use for general cleaning around the house. Just about all synthetic sponges have the chemical Triclosan in them which is classified by the EPA as a pesticide
