Method for cleaning a soiled article

A process for the machine-washing of fabrics according to which a dispensing and diffusing device of the reusable type is filled with a particulate product which is active during the washing. This device is placed in the machine together with the fabrics to be washed, and washing is subsequently carried out in the customary way. The device used comprises a flexible bag mounted on a ring made of plastic with helical radial walls providing apertures through the mouth delimited by the ring. A assembly in the form of a cage can be arranged inside the sleeve of the bag in order to maintain the form of the latter during the washing. The product dissolves progressively and little escapes from the device in solid form.
