Super Kleen Carpet Rinse And Neutralizer, Quart. A specially formulated product with Soil Guard 2000, used to rinse the carpet after extracting cleaning, shampooing, or bonnet buffing. This necessary step will remove any residual remaining in the carpet fibers and will further rinse on the acid side to prevent the carpet from oxidizing (turning brown), leaving a pleasant scent. Excellent for coffee, tea, and light rust stains. Safe on all carpet fibers including wool. Does not contain any optical brighteners. The new Soil Guard 2000 cleaning technology incorporates DuPont Zonyl Soil and Stain Protector to deliver a product that neutralizes harsh alkali residues from previous cleanings, removes detergent residues from the fibers and gives the dry carpet a fresh clean feel.
