Microfibers are the newest in cleaning technology. The small "micro" fiber is no more than 100th the size of a human hair. The microfibers are woven together and then split into a wedge-shaped filament. This greatly increases the surface area of the towel and actually picks up dirt instead of pushing it around. Microfiber cloths work exceptionally well with just water and without using harmful chemicals. Microfiber can hold 7 times it's own weight in liquid. Microfiber cloths will not lint, can be rewashed many times over for extra added value and won't scratch delicate surfaces. Use anywhere on anything! U.S. Wiping's Microfiber Towel also comes in 10 appealing colors to help control cross-contamination. Use 1 color for T.V.'s and computer screens and another color for heavy duty cleaning. Please call us at 1-800-279-2051 if you have any questions or would like further information. While we only offer 16" x 16" microfibers online, we certainly can offer you other sizes and constructions. Just let us know and a customer service specialist will be glad to assist you.
