If You Care Sponge Cloths are made in a proprietary process from a three-dimensional blend of cellulose, unbleached cotton. Extremely porous, which makes the sponge extremely absorbent. It can absorb up to 20 times its own weight in water. There is no better or more effective cleaning cloth for kitchens, countertops, bathrooms, and general household cleaning available anywhere. If You Care sponge cloths do not leave streaks. They absorb liquids easily and quickly and release them with a simple wring. They are remarkably durable, resistant to tears and abrasions, reusable over and over again. It is recommended to rinse the cloth and wring out excess water to increase absorbency. Use with water, soap and water or any household cleaner. After use, rinse well, drain off water and lay flat to dry. Fabric can be washed at temperatures up to 1900F (880C) in a dishwasher or washing machine with normal loads. Do not use chlorine bleach or chlorine products. After washing, let it air dry.
