What makes microfiber cloth superior? Microfibers are single fibers thinner than a human hair split 16 times. One of the most absorbent materials in existence, microfibers trap dirt, grime, and liquids instead of pushing them around. Debris trapped in the fibers can be washed or rinsed away. Microfiber cloths can be washed upwards of 300 times without losing their cleaning and trapping power.
