Abstract
A cleaning means is disclosed for textile surfaces, particularly textile floor coverings, containing a powdery, porous carrier material based upon urea-formaldehyde-resin foam which is enriched with cleaning agent, whereby the tenside-containing water adhered within the carrier material from the foaming-up process is stored completely homogeneously in the carrier material, and forms together with the cleaning agent the prepared product. It is suggested for lowering the free formaldehyde content, to add to the tenside-containing water adhering within the carrier material, a salt of sulfurous acid in an effective portion, relative to the anion of the acid, from 0.01-2% by weight. This strongly reduces the portion of free formaldehyde and adjusts the pH-value of the cleaning means between 6 and 9.
