Occasionally, we find that people are surprised that handmade rugs are as durable as they are. They can withstand generations of use and enjoyment while needing just a minimal amount of care, including regular vacuuming, inspection, and periodic rotation and professional cleaning. There are times, however, when an Oriental rug can benefit from more than just a regular professional cleaning (which we recommend as once every two years in most circumstances). Among these times are when a rug is infested by moths, when it has been soiled by pet urine, when it has been damaged by a flood or sitting water, or when it has not had a professional cleaning for an extended period of time. In these instances, we recommend a professional cleaning with an additional treatment, such as overnight soaking. An extended soaking, for example, can help eliminate the foul odor that results from the wool being urinated upon. Generally, a professional cleaning would not suffice to achieve this results.
With just a minimal amount of care, one can extend the life of an Oriental rug by decades, even centuries in some instances. -www.traditionalrugrepair.com
