(57) The present invention discloses a glass bottle cleaning additive and cleaning method
for glass bottles, for use in treatment by cleaning glass bottles in a primary caustic
tank and a secondary caustic tank, 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 is added in the primary caustic tank, the component
B is selectively added in the primary caustic tank, the component A and the component
B are added in the secondary caustic tank, and the component C is selectively added
in the primary caustic tank or the secondary caustic tank. The addition amount of
the component A is 0.05%-0.5%, the addition amount of the component B is 0.1 %-0.5%,
and the addition amount of the component C is 0-0.5%, based on the weight of an caustic
solution added in the primary caustic tank or the secondary caustic tank. The caustic
solution in said primary caustic tank and said secondary caustic tank is a 1.5%-3%
sodium hydroxide solution. The glass bottle cleaning additive and cleaning method
for glass bottles of the invention enable a stable and good cleaning effect at a relatively
low temperature, usually 50-70°C.
