Caring for the Niels Rug - Regular vacuuming and the occasional gentle shake should keep your rug in shipshape condition. When vacuuming, set vacuum so that the brush is the furthest away from the surface of the carpet. This rug contains viscose so it is best to avoid exposure to moisture of any kind, as this may cause permanent staining. Best suited for low traffic areas or homes without children or pets.
