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.

[ What is claimed:] [1.] A method of cleaning textile fibers which comprises applying to said fibers, an internally-carbonating cleaning composition at ambient pressure and at an elevated temperature of at least 140.degree. F. said composition being prepared coincident with said application by combining solutions at said elevated temperature consisting essentially of(a) an aqueous carbonate salt solution comprising 0.1 to 16% by weight of a carbonate salt, said carbonate solution having a pH of between about 8 and 11; and(b) an aqueous acidic solution comprising 0.1 to 16% by weight of an acid, said acidic solution comprising an acid having a pH of between about 3 and 6 wherein the relative proportions of carbonate salt, and acid are such that the carbonate reacts with the acid when said solutions are combined so as to create an aqueous composition having a generally neutral pH and from which carbon dioxide is released into the surrounding atmosphere causing carbon dioxide to come into contact with said textile fibers.
