Abstract:
1. A method of polishing an object to be polished, the method comprising: preparing a polishing composition containing at least abrasive grains and water; using the polishing composition to polish the object; and washing the object after polishing to remove abrasive grains that attach to and remain on a polished surface of the object after polishing, wherein the relationship X1×Y1≦0 and the relationship X2×Y2>0 are satisfied, where X1 [mV] represents the zeta potential of the abrasive grains measured during polishing of the object by using the polishing composition, Y1 [mV] represents the zeta potential of the object measured during polishing of the object by using the polishing composition, X2 [mV] represents the zeta potential of the abrasive grains measured during washing of the object after polishing, and Y2 [mV] represents the zeta potential of the object measured during washing of the object after polishing.
