A carpet cleaning preparation in the form of a dry cleaning preparation in powder form which contains surfactants, organic solvents and zeolite and which is characterized in that the zeolite is in the form of a porous granulate which is unaffected by the mechanical stresses normally encountered during dry cleaning. The zeolite is preferably in the form of a porous granulate containing less than 2% by weight of particles 0.05 mm and smaller in size and less than 5% by weight of particles larger than 2 mm in size.

A dry cleaning preparation in powder form for cleaning carpets and fabric which preparation consists essentially of (a) from 40 to 90% by weight of zeolite, (b) from 0.5 to 15% by weight of at least one surfactant, (c) from 5 to 30% by weight of at least one organic dry cleaning solvent, (d) from 1

A dry cleaning preparation in powder form for cleaning carpets and fabric which preparation consists essentially of (a) from 40 to 90% by weight of zeolite, (b) from 0.5 to 15% by weight of at least one surfactant, (c) from 5 to 30% by weight of at least one organic dry cleaning solvent, (d) from 1 to 20% by weight of at least one granulating aid, (e) from 0 to 10% by weight of at least one solid, water-soluble acid, and (f) from 0 to 10% by weight of other customary constituents of dry cleaning preparations in powder form, wherein at least components (a), (d), and (e) are combined to form a porous zeolite granulate which withstands the mechanical stressing normally encountered in dry cleaning and containsless than 2% by weight of particles 0.05 mm in size and smaller and less than 5% by weight of particles larger than 2 mm as determined by sieve analysis and have a mechanical stability when subjected to a vibrating ball mill filled with about 5 porcelain balls 28 mm in diameter for 1 minute at 1400 rpm and then sieved, such that the proportion of particles up to 0.2 mm in size increases to no more than 15% by weight, based on the total weight of the granulate, and wherein this granulate is then united with components (c), (f) and the remaining parts of (b). A process for cleaning carpets and textiles, characterized in that the dry cleaning preparation of claim 1 is applied to the textile in quantities of from 20 to 200 grams per square meter and is intensively rubbed into the textile for 0.5 to 2.5 minutes per square meter, the soil and cleaning preparation combining with one another, after which the residues are mechanically removed from the textile.
