Carpeting, upholstery, drapery and other textile fibers are cleaned by applying to the fibers, from a pressurized container, an aqueous internally carbonated non-surfactant cleaning composition prepared by admixing, by volume, about 1 25 ml (150 grams) of an alkaline metal bicarbonate or percarbonate salt, about 62. 5 ml (57.4 grams) of a carbonate salt and about 187.5 ml (165 grams) of a natural solid acid, in an aqueous medium such that the natural solid acid reacts with the carbonate/bicarbonate salts to produce carbon dioxide and the solids concentration in the solution resulting from the carbonate salts and natural solid acid forming the basis of the cleaning solution. Citric acid, sodium carbonate and sodium bicarbonate are the preferred solid acid and carbonate salts. The composition is prepare d from naturally occurring ingredients and the container is pressurized by air or other environmentally safe gaseous materials. It may be used as a heated or ambien t temperature cleaner, to the best advantage of each situation.
