せないようにすることである。As described above, the cause of white turbid stains (whitening) on the surface of a glass bottle when the glass , for example, the glass bottle is washed by the washing machine, is that the silicic acid component present in the detergent aqueous solution in the washing tank is caused by the bottle. This is because it adheres to the surface, and this is combined with the glass surface by drying to form an insoluble silicate scale. Therefore, in order to prevent the whitening, it is necessary to prevent the glass surface from being dried until the silicic acid attached to the glass surface is washed away.

防止効果については全く知られていなかった。The present invention is particularly characterized in that a cleaning agent containing a specific polyhydric alcohol component is used as a strong alkali cleaning agent comprising an alkali metal hydroxide and a sequestering agent. This polyhydric alcohol component maintains the moisture of the bottle surface for a long time without adversely affecting the cleaning effect of the strong alkaline cleaning agent. This polyhydric alcohol has been conventionally used as a solubilizing agent in a bottle detergent composition, but it is not yet known that it has a remarkable action and effect in preventing cloudiness, and in particular, it prevents propylene glycol and glycerin from clouding. No effect was known at all.

To 6) were diluted to prepare a washing aqueous solution. After the cleaning aqueous solution was heated to a temperature of 70 ° C., a brown glass piece was immersed in the aqueous solution. Next, this was taken out of the aqueous solution and dried in a drier, and a clouding phenomenon on the glass surface was observed. After the observation, rinse the surface of the glass piece with warm water to wash away the detergent.Using the same colored glass piece, repeat the same immersion, drying, observation, and warm water rinsing until the opacity phenomenon on the glass piece surface is observed. And the results are shown in Table 1. In Table 1, the sample No. 2 and 3 are original
The composition of the cleaning agent used in the method of the present invention is shown.

This artificial stain plate was immersed in a diluted aqueous solution of each sample shown in Table 3 heated to 70 ° C. for 10 minutes, then immersed in warm water for rinsing, and the residual stain on the washed surface after drying was measured with a gloss meter. did. The cleaning efficiency was calculated based on the glossiness of the artificial stain plate before washing and the glossiness of the glass surface after washing, and compared.
