Vacuum regularly on "floor" setting, without a beater bar. Clean by blotting with a soft cloth and mild soap. Rinse well with an outdoor hose. Hang until thoroughly dry. If a loop is pulled by a pet, furniture leg, high heel, or vacuum suction, it will affect other loops in the same row. This is not a defect and you can gently pull the yarns in the row to return to the original position.
