Aramith Micro-Fiber Cloth: The Aramith Micro-Fiber Cloth is much more than a regular cloth! Features: High cloth resistance: strong fiber with "w" anchorage within the textile structure; this velvet structure means no fibers will be lost on the ball surface. Absorption: absorbs 4x its weight in water, 8x its weight in grease. Fiber thickness: 0.6 g/10.000 m insures excellent cleaning performance; even inside small surface defects or scratches. Fiber shape: the curly shaped fibers easily remove dust from the ball's surface and capture dust into the microfiber through electrostatic effect due o friction on the ball's surface. Fiber height: 3 to 4 mm. High fiber density: 40,000 fibers/cm2, insure excellent cleaning and polishing. High dimensional stability: no shrinkage after hot wash (60 C/140 F). High fiber crush resistance: recovers its initial volume and absorption after use. Maintenance: Wash at 60 C / 140 F when suitable. No ironing: ready to use after washing.
