We recommend sending your rug to a reputable professional who is accustomed to cleaning rugs of this quality when your rug appears dirty or has set-in stains. We do suggest taking immediate action in the case of spills to lessen stains. Most stair runners are made of various synthetic and natural materials, we recommend having them cleaned by an IICRC certified cleaner.
