Premium Microfiber cloths aren't just cloths - they're a gateway to effortless cleaning, drying and polishing power at your fingertips. Muc-Off Microfiber cloths contain 'split-fiber' technology, that vastly increases surface area absorbency to easily eliminate smears and blemishes. Microfibers trap dirt deep in the pile of the cloth which helps to avoid the chance of swirling, which could lead to damaged paintwork. These handy cleaning cloths are machine washable.
