Abstract
A process for the removal of stains from fabrics, such as carpets. The process comprises treating the stained areas of the fabrics with a liquid, paste-form or foam-form stain remover and subjecting the entire fabric to cleaning with a powder-form cleaning composition before the treated areas have dried. The preferred stain remover is an aqueous composition containing a surfactant, and the preferred powder-form cleaning composition contains a finely divided cellulose powder as an adsorbent. The new process is suitable above all for the cleaning of carpets and carpeted floors.
