  • Patent number: 5718729
    Abstract: Carpeting, upholstery, drapery and other textile fibers are cleaned by applying to the fibers, at ambient pressures, an aqueous, chemically carbonated cleaning composition prepared by admixing a carbonate salt solution, and an acid solution, such that the acid reacts with the carbonate salt to produce carbon dioxide coincident with application to a textile to be cleaned. Citric acid and sodium carbonate are the preferred acid and carbonate salt. In a preferred embodiment, urea is added to the acid solution to prevent yellowing and to improve cleaning ability. The compositions are preferably prepared and applied at an elevated temperature in the range of between about 140.degree. and 200.degree. F.
