A cleaning method for glass bottles, by using a cleaning additive, said cleaning additive consisting of a component A, a component B and a component C, wherein the component A contains an organic phosphine chelating agent, the component B contains a peroxide, and the component C contains an antifoaming agent, to clean glass bottles, comprises the following steps: (i) adding the component A containing an organic phosphine chelating agent to an caustic solution of a primary caustic tank, selectively adding therein the component B, and mixing them thoroughly; adding the component A containing an organic phosphine chelating agent and the component B containing a peroxide to the caustic solution of a downstream secondary caustic tank, and mixing them thoroughly; (ii) immersing glass bottles in the primary caustic tank, to sufficiently contact with a mixed solution in the primary caustic tank; (iii) transferring and immersing the glass bottles into the downstream secondary caustic tank after they have left the primary caustic tank, to sufficiently contact with a mixed solution in the secondary caustic tank, and selectively adding the component C containing an antifoaming agent; and (iv) moving the glass bottles out of the secondary caustic tank, and subjecting them to spray cleaning, wherein in said steps (i)-(iii), the temperatures in the primary caustic tank and the secondary caustic tank are 50°C-70°C, and wherein component A also comprises any one or a mixture of two or more of gluconate, gluconic acid, lactic acid and citric acid. said cleaning additive consisting of a component A, a component B and a component C, wherein the component A contains an organic phosphine chelating agent, the component B contains a peroxide, and the component C contains an antifoaming agent, the component A contains an organic phosphine chelating agent, the component B contains a peroxide, and the component C contains an antifoaming agent, to clean glass bottles, comprises the following steps: (i) adding the component A containing an organic phosphine chelating agent to an caustic solution of a primary caustic tank, selectively adding therein the component B, and mixing them thoroughly; adding the component A containing an organic phosphine chelating agent and the component B containing a peroxide to the caustic solution of a downstream secondary caustic tank, and mixing them thoroughly; (ii) immersing glass bottles in the primary caustic tank, to sufficiently contact with a mixed solution in the primary caustic tank; (iii) transferring and immersing the glass bottles into the downstream secondary caustic tank after they have left the primary caustic tank, to sufficiently contact with a mixed solution in the secondary caustic tank, and selectively adding the component C containing an antifoaming agent; and (iv) moving the glass bottles out of the secondary caustic tank, and subjecting them to spray cleaning, (i) adding the component A containing an organic phosphine chelating agent to an caustic solution of a primary caustic tank, selectively adding therein the component B, and mixing them thoroughly; adding the component A containing an organic phosphine chelating agent and the component B containing a peroxide to the caustic solution of a downstream secondary caustic tank, and mixing them thoroughly; (ii) immersing glass bottles in the primary caustic tank, to sufficiently contact with a mixed solution in the primary caustic tank; (iii) transferring and immersing the glass bottles into the downstream secondary caustic tank after they have left the primary caustic tank, to sufficiently contact with a mixed solution in the secondary caustic tank, and selectively adding the component C containing an antifoaming agent; and (iv) moving the glass bottles out of the secondary caustic tank, and subjecting them to spray cleaning, wherein in said steps (i)-(iii), the temperatures in the primary caustic tank and the secondary caustic tank are 50°C-70°C, and wherein component A also comprises any one or a mixture of two or more of gluconate, gluconic acid, lactic acid and citric acid.
