A microfiber cloth pack contains towels made from a blend of polyester and polyamide fibers, split to be finer than a human hair. Unlike cotton, which pushes dirt around, microfiber traps dust and moisture deep within its split fibers. These packs usually contain different GSM weights: lower plushness for interior cleaning and removing wax, and high plushness for drying the car without scratching soft paint. They are washable and reusable but must never be washed with fabric softener.
