Due to its chemical nature, Sorona does not chemically react with the fiber itself, giving it permanent stain-repellent properties that will not be lost by prolonged use. In addition the carpet is a whole structure, composed of carpet fluff, lining and bottom back and other structures. Sometimes the stain penetrates into the bottom of the carpet, even though the carpet pile has been cleaned during cleaning, but the stain will continue to "siphon" to the pile of the carpet as it dries, leaving the carpet dirty. If it is found that the stain disappears during the washing process and appears again after drying, the infiltrated stain on the bottom of the carpet is not cleaned and requires 2 washes.
