Nourison recommends only the use of Woolite or other compatible Carpet Cleaner for the cleaning of allrugs. The cleaning process should involve applying the Woolite with a soft bristle brush, rinsing the water, and extracting with a vacuum or extractor. The rug should then be dried by air or low temperature hair dryer. The use of any other cleaning solvent will void the Nourison warranty, and make the cleaning service solely responsible for any damage caused to the rug. Nourison does not guarantee that these methods work and should be used as a guideline only!? If in doubt, call a reputable cleaner.
