Another significant benefit of R2X is its effectiveness with polypropylene. Most polypropylene carpets have an inherent tendency to attract soil. Topical soil treatments are only "skin deep, " and the limited protection they offer wears away after cleaning or normal wear and tear. In contrast, R2X continues to perform well even after repeated cleanings-with both nylon and polypropylene-when the performance of ordinary systems begins to diminish. And of course, Shaw's warranty protection ensures customer satisfaction, time after time.
