Abstract
A liquid or dry, flowable cleaning composition for carpeting is provided which comprises: (1) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid, or mixtures of water, surfactant and organic liquid; and (2) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets. In the case of a dry-type composition sufficient particulate material is added to provide a dry, flowable product.
