With all the choices out there this can be a difficult decision, polyester, olefin, wool or nylon? The overwhelming choice should be nylon. Polyester and olefin fibers break down quickly and the new carpet luster is soon lost, after only a year or two most consumers who purchased polyester deeply regret not paying a little more and getting a nylon carpet. Wool is very expensive and stains very easily due to the high amount of dye sights, hence most wool rugs have elaborate color designs because they readily accept staining material. A moderate quality nylon carpet with a continuous fiber will give you years of wear and tear, it cleans up beautifully and in most cases even the hardest hit areas can look like new after a thorough deep clean by Ace Chem-dry.
