But there are certain signs that are indicative of an unclean rug. Some of these signs include a fading rug, a rug that feels rough, and stains that have been on your rug for a long time, even after multiple cleaning sessions. If you spot these signs, it’s time to get in touch with professional rug cleaners to get your rugs cleaned up.
