The invention provides a stress-free water-washing chiseling method, and belongs to the technical field of concrete surface chiseling. The method comprises the following steps of, carrying out comprehensive inspection on formwork before construction, preparing chiseling solvent, cleaning the surface stains of the formwork, using a brush to uniformly coat the prepared chiseling solvent on the formwork in a part to be chiseled, smearing the formwork uniformly, and fabricating the formwork for pouring concrete after the air drying of the chiseling solvent; removing the formwork after the concretestrength reaches the specified requirement of the corresponding structure; immediately washing away the laitance with high-pressure water after removing the formwork, and exposing aggregate; and checking whether there is a place where the chiseling solvent is not applied, wherein the chiseling solvent is a mixture containing hydroxyl groups, and the chemical formula of the chiseling solvent is C12H22O11. The method solves the problems of poor effect, low efficiency, high cost, large noise, dust pollution and the like of the traditional concrete chiseling process.
