Faux fur throws provide the heavyweight warmth you need when nights turn chilly. Artificial fur is usually made of synthetic materials such as acrylic, modacrylic and polyester, though some faux fur blankets include cotton, wool, rayon or silk. If you do not know the fiber content of your blanket, consult a professional cleaner, but you can wash synthetic faux fur fabric at home.
Use a top-loading washing machine for best results when cleaning faux fur blankets at home. Set the machine to the delicate cycle and fill it with cold water. As the machine fills, add mild laundry detergent, such as a formula created for delicate fabrics. Use a detergent free of fabric softeners, and do not add fabric softener to the rinse cycle. Place the blanket in the machine and allow the cycle to complete.
Because faux fur absorbs so much water, your blanket may need a second spin cycle. Top-loading machines allow you to turn the dial back and spin the blanket again if necessary, but you can repeat a spin cycle on some front loaders, as well. When you have removed as much water as possible, take the blanket outside and hang it over a clothesline or railing to dry. If you do not have outdoor access, drape the blanket over the back of two or more wooden or metal chairs. Always allow faux fur to air dry, as placing it in the dryer can damage it. Shake the blanket out after drying to fluff it again.
