Our Indoor Doormat is made of high-quality absorbent polypropylene fabric, uses double layer technology which absorb moisture and dirt from shoes quickly, makes your floors clean and dry. And the non-skid TPR rubber backing won't scuff floors, perfect for both indoor and outdoor use. The unique rib fabric design removes dirt from shoes easily. When your doormat gets dirty, first shake it off outdoors or over your garbage bins, then sweep with a broom or vacuum regularly or use a garden hose to rinse the mat outdoors. For deeper clean: machine washable, use water under 86 (℉) / 30 (℃). Do not iron. Do not bleach. Do not expose it to the sun for a long time. Since the doormat was folded up during transportation, it’s normal to see there will be two creases on the rug. Please lay it flat for 2 to 3 days and wait patiently for its recovery.
