The invention discloses a solid cleaning product, which is prepared by the following steps of: grinding natural plant peel, pericarp, husk and shell materials such as shells, durian shells, litchi pericarp, oyster shells, pineapple peels, buckwheat husks, aloe peels, orange peels and cinnamon bark into particles with 20 to 600 meshes serving as scrub materials, and adding one or more scrub materials into a soap base by adopting low temperature saponification technology to prepare the scrub soap. In the process of preparing the scrub soap, surfactants and chemical additives are not added at all, and byproducts are not generated at all, so the scrub soap cannot have any adverse effect on the skin and environment. The pericarp, husk or shell scrub material in the scrub soap can peel off or remove dead skin cells, contains rich natural active ingredients such as polysaccharides, vitamins, tartaric acid and pectin, which have good effects of sterilizing, beautifying, moistening, repairing and resisting ageing on the skin, and has great market application prospect.
