ABSTRACT:
Carpeting, upholstery, drapery and other textile fibers are cleaned by applying to the fibers, from a pressurized container, an aqueous effervescing internally carbonated non-detergent cleaning composition prepared by admixing, in percent by weight, about 20 to 60% of a carbonate salt, about 20 to 60% of a natural solid acid, and 5 to 40% urea in an aqueous medium such that the natural solid acid reacts with the carbonate salt to produce carbon dioxide and the solids concentration in the solution resulting from the carbonate salt, natural solid acid and urea is between about 0.5 and 10% by weight. Citric acid and sodium carbonate are the preferred solid acid and carbonate salt. The composition is prepared from naturally occurring ingredients and the container is pressurized by air or other environmentally safe gaseous materials.
