Micro fiber cloth is a synthetic knit fiber of very small threads. The cloth is both soft and abrasive at such a micro level that you canot feel it. Since it is made of so many small fibers, it is very absorbent, yet can be wrung almost dry like a chamois (shammy). Since it is synthetic, it holds dust, dirt, and bugs well, but rinses out easily, with very little being absorbed into the cloth.
