The Chenille Microfiber Premium Scratch Free Wash Mitt is made of thick microfiber strands that are woven into Big Fat Plump, caterpillar strands that are extremely absorbent to wash soaps and shampoo and non-abrasive to paint and finishes. The chubby spun strands hold loads of soapy water delivering a premium wash that lubricate the paint, reducing friction and enhancing paint. This mitt is easy to wash using your favorite detergent. Toss them right into the washing machine for easy care. Just be sure to wash them separately, to keep them lint free. As with all microfiber products, never expose them to fabric softener. Fabric softener will reduce their static properties and cause the microfiber to clean/spread less effectively. They can be line dried or machine dried on low setting, again, separately from other laundry.
