Synthetic sponges are poisonous! Almost every synthetic sponge now sold in U.S. supermarkets is impregnated with a disinfectant—usually trisclosan. Triclosan is a pesticide that is registered with the Environmental Protection Agency (EPA). Not only should we be concerned about washing our dishes and counter tops with triclosan, but common disinfectants may contribute to drug resistant bacteria just like antibiotics. Synthetic sponges inhibit bacteria, mold and mildew; Sea Sponges are permeated with natural enzymes that inhibit the growth of mold, mildew and bacteria. Durability; A properly cared for sea sponge will last for many months. Most synthetic sponges fall apart, shrink and become infested with bacteria and mildew in less than one week. Natural sponges fit into a green and organic lifestyle. Sea sponges are sustainably harvested. When sponges are collected, part of the sponge is left on the ocean floor to grow back. Through crop rotation, sponges are harvested over and over again as they regrow to their original size within a few years.
