Abstract
The present invention relates to a cleaning implement based on melamine-formaldehyde foam comprising hollow microspheres, wherein said hollow microspheres have a median particle diameter (D50, volume averaged, Malvern, Fraunhofer diffraction) in the range from 260 μm to 490 μm, and wherein the hollow microsphere are at least partly filled with a benefit agent. Additionally the present invention encompasses a method for cleaning a hard surface with a cleaning implement according to the present invention.
