We purchased a wool Kenneth Cole rug and it was completely defective. It is unable to be cleaned, even with wool cleaners, without causing massive yellowing and staining. We have purchased wool rugs in the past and never had this problem. We literally threw more than $1000 down the drain as the rug became unusable a few days after buying it and we were forced to throw the rug away. Steer clear of Kenneth Cole rugs at all costs!
