The invention relates to a washing product containing attaching clastics, which is formed by adding a certain proportion of the clastics into a daily washing product, such as a soap, laundry powder, washing cream, liquid soap, tooth paste, a facial cleanser and the like. The clastics can be flora and fauna scraps, mineral matter scraps and scrap matters formed by various types of production and processing. Chemical components of the clastics are stable and harmless to human bodies, and are free of harm reaction with the washing product and pollutant components. The attaching clastics have certain compatibility and adsorbability against pollutants, are strong in pollutant adhesion, can be called as the attaching clastics, and play the roles of adhering, adsorbing and scratching the pollutants, thereby being more conductive to improving a cleaning effect. The particle size, the shape, the hardness and the like of the attaching clastics are suitable for the skin of human bodies for use. The particle size ranged from plural microns to plural millimeters, the shape can be a sub-edge angle, a sub-circle, grains, a sheet and the like, the hardness is relatively low, and the density is lighter. Physical indexes are appropriate, so that the pollutants can be mechanically stripped from the human bodies or objects to be cleaned by taking the clastics as carriers.
