The best microfiber cleaning cloth, Euro Clean, non woven.
Cleaning products, microfiber can be 100% polyester, or a blend of polyester and polyamide (nylon). It can be both a woven product or a non woven product, the latter most often used in limited use or disposable cloths. In some of the highest-quality fabrics for many cleaning applications, the fiber is split during the manufacturing process to produce spaces in each fiber. If one were to look at a cross section of many split microfiber fabric under extreme magnification, it would look like an asterisk. It’s the split fiber, and the size of the individual filaments working in conjunction with the spaces between them that does the work. They pick up and hold the dust and dirt, and absorb liquid.
Unlike cotton, microfiber leaves no lint, the exception being some micro suede blends, where the surface is mechanically processed to produce a soft plush feel.
For microfiber to be most effective as a cleaning product, especially for water soluble soils and waxes, it should be a split microfiber. If microfiber isn’t split during manufacturing, it isn’t much more than a very soft cloth, duster, or mop, with one major exception. For the removal of skin oils, (sebum), sunscreens, and mosquito repellents from prescription eyeglasses, camera lenses, and optical surfaces in general, higher end proprietary woven, 100% polyester cloths using 2 µm filaments, will absorb these types of oils quickly and easily without smearing.
Microfiber that is used in non sports related clothing, furniture, and other applications isn’t split because it isn’t designed to be absorbent, just soft. When buying from a retail store, if the packaging doesn’t say its split, don’t assume it is. Note: The majority of microfiber cloths being sold for cleaning will not designate on the packaging, whether or not its is constructed of split fiber. So, one quick way to determine if the microfiber is split, is to run the cloth lightly over the palm of your hand. If the cloth “grabs” the imperfections on your skin (one can actually both “hear” and feel it grab), then it’s split. Another way is to pour a small amount of water on a hard flat surface and take a towel or mop and try to push the water. If the water is pushed rather than being absorbed, it’s not split microfiber. If the water is absorbed or drawn into the fabric, then it is likely a split microfiber.
In addition to the open spaces in the fibers created during the splitting process, microfiber is an effective cleaning tool because the fibers are positively charged. Dirt and dust are negatively charged so they are attracted to microfiber like a magnet. The microfiber holds on to the dust and dirt until it is released in the laundering process or when it is rinsed out.
