Several synthetic and natural materials produce machine-washable carpets and rugs. Cotton is one of the rare natural fabrics that you can wash in the washer; however, it takes longer to dry, and it’s more expensive than synthetic rugs. Olefin, nylon, polyester, polypropylene are all synthetic materials you can just throw in the washing machine without fearing that you’ll damage them. These are quite durable materials that dry fast. Also, you can feel free to hand-wash them whenever you want. Viscose is another common rug material. Many people are under the false impression that viscose is a synthetic fabric, but that’s not 100% true. It’s actually a blend of natural and synthetic fibers. If you ever want to machine-wash a viscose rug, you should check the manufacturer’s instructions. Since it’s not 100% synthetic, it is a gentle material that requires extra care.
