Micro fiber is a technological marvel created out of polyester polyamides. Yes I know. For years I've told you 100% cotton is the only thing that should touch your paint. A unique design has made this material safe. Each fine fiber is several hundred times smaller than a strand of cotton! This creates non-abrasive ends which are super soft and provide many additional benefits. Micro fiber absorbs seven times its weight in liquid and soaks up water like a chamois. Ideal for Speed Shine® wiping and drying. The non-abrasive, wedge shaped micro fibers, lift and trap wax and polish better than cotton and are lint-free. This makes wiping go faster. Made in many grades from cheap to premium, our micro fiber is the finest and has been tested thoroughly. Machine wash and dry (don't use fabric softener, bleach or iron). Wonderful for dusting too. Set includes six cloths; color coded for Best of Show Wax® and Speed Shine® (white) and Polish (yellow). For those of you that still like our 100% Cotton Buffing Cloths, don't worry we won't stop selling them. But, these Cloths are certainly worth your while to try out. A generous 16" x 16" square. My favorite, and they will be yours, too. Woven especially for Griot's Garage and imported just for you.
