Why microfiber scrubber sponges? The microfiber material is made of high-tech fibers, which are super soft and lint free, and provide more cleaning power than normal sponges. With 85% polyester and 15% polyamide (nylon), the fiber is designed to enlarge the wiping area. It’s great for dusting and removing dirt. The scrubber is woven with PP/polyester, instead of metal fiber, for a complete, non-scratch clean that protects your utensils. The sponges have a 20D density with high resilience for superior absorbency. The microfiber and scrubber material improve the function of the cleaning sponge and protect it for longer use. How to use: Use the soft side to remove hair, dust work surfaces, and absorb moisture. Use the scrubber to remove hard-to-clean stains with water. Detergent can be used for tougher, greasy, or baked-on messes. Dry before storing. Where to use: Great for washing basins, bathroom sinks, dishes, window frames, and cars; and for dusting shoes. Assorted 8-pack includes different colors for different areas of the house to keep everything separate and sanitary. 100% Money Back Guarantee We are very confident you will save time cleaning with these functional sponges.
