The E-Cloth Glass & Polishing Cloth gives the ultimate finish to windows, mirrors, chrome and all shiny surfaces, by working to remove light grease, fingerprints, dirt, and over 99% of bacteria, with just water. Fold the cloth and use it as a pad to ensure good contact with the surface and have a number of different cleaning sides. Use the cloth dry on damp surfaces to absorb water remnants and leave the surface with a streak-free shine. In between uses rinse with warm water and hang dry, and machine wash in hot water weekly. Like you, we think cleaning should be pure and simple. A healthier way to clean, E-Cloth is enough.
