Carpet Extraction Rinse SC effectively removes and flushes out hard water deposits and neutralizes residue from previous cleanings. Special, slightly acidic formula makes salt residue more soluble to more easily remove winter salt without left-behind residues or clogging., Versatile rinse is strong enough for advanced-generation carpet fibers at low dilution, yet delicate enough for wool carpets at high dilution. Use safely on most colorfast carpets. Enjoy a refreshing fruity scent.
