The aim of the invention is to improve the cleaning power of washing and cleaning agents, especially with regards to bleachable stains, while avoiding any damage to the textile treated with said washing and cleaning agents. This is achieved by an aqueous washing liquid in a device for cleaning textile substrates, containing a plurality of water in-soluble solid particles and a mediator compound, which can produce an oxidizing bleaching agent, in an electrochemical cell using electric voltage in the washing liquid.

Device for use in the treatment of textiles or leather with liquid, comprising a container having an inner wall with through-holes and surrounded by a spaced outer wall, with lids covering the terminal cross-sectional openings of the container, with a drive which drives the container along a trajectory curve to a reciprocating movement with a maximum acceleration of at least 20 m/s.sup.2.
