Abstract: A spray arrangement, particularly a brush-like body-cleaning and/or massage device, particularly a toothbrush (1) with at least a nozzle body (10') may be coupled to a hollow handle which is connectable by a hose to a water faucet. Nozzle body (10') is preferably a fluidic oscillator without moving parts. The hollow handle may receive into a metering cartridge a rod of a slow-to-dissolve active substance. The handle is provided with a removable elongated cap whose forward end may be coupled securely irrotationally with tube (5) of the cleaning brush. Moreover, the cap includes a manually actuatable water valve which is manually displaceable into the open position against a spring force and/or opposing water pressure. The water valve is preferably formed as a multi-step slide valve piston (68) with a conical shut-off member (72).
