A composition for treating hard surface includes (a) a liquid silica sol, wherein the solid content of Si02 is 51%~99.9% by total solid weight of the composition, (b) a solid inorganic gel having nano-scale layered, chained, layered and chained, or framework structure, wherein the weight of which is 0.1%-49% by total weight of the composition, (c) a dispersing medium, wherein the weight of which is 1%-50% by total solid weight. A method for treating hard surface includes the steps of preparing the above-mentioned, coating the composition on the hard surface, and polishing the coated hard surface. |
