A valid question! Frequent cleaning of your carpet and upholstery will lengthen the life of your investment. It relieves stress to the fabric from body oils, dirt, and other foreign bodies. It maintains a clean smell for the fabric and makes it more comfortable during regular use. But fabric cleaning may not be the best do-it-yourself project! Most fabrics are very temperamental and can easily bleed, wear, or stain without using the proper best practices. Allow NOVA the opportunity to give your carpets and upholstery the care they need to last longer and protect your investment!
