Description All- purpose Cellulose Sponge are made in a patented process from a three dimensional blending of cellulose, non-GMO unbleached cotton and mirabilite – a natural mineral salt. During the production process, the mirabilite is washed out, leaving the remaining blend (70% cellulose & 30% cotton) extremely porous, which makes the sponge extraordinarily absorbent. It can absorb up to 20 times its own weight in water. The sponge absorb liquids easily and quickly and release them with simple wringing.They are remarkably durable, tear and abrasion resistant, reusable over and over again, and can be machine or dishwasher washed in water up to 140F (60C). Each cloth is reusable and washable many times. These sponge cloths reduce waste and the amount of material going to landfill. The packaging is recycled and sponge is fully biodegradable. Use & Care Rinse before first and after each use. Use with water, soap and water, or any household cleaner. After using, rinse thoroughly, wring out water, and leave flat to dry. After washing, leave to air dry. Do not tumble dry.
