態とした。 Example 1 Soil of oil and fat A soybean oil of 0.1 g was uniformly applied on a stainless steel plate of about 40 cm 2 to prepare a soil plate. Each of the stained plates was left uncleaned, incompletely cleaned, or completely cleaned.

いだ状態である。"Uncleaned" refers to a state in which the dirty plate is left as it is, "incomplete cleaning" refers to a state in which the dirty plate is exposed to running water for 1 minute, and "complete cleaning" refers to a condition in which the dirty plate is heated to 80 ° C. After being immersed in a 2% NaOH aqueous solution for 10 minutes, it is rinsed with running water.

結果を表１に示す。The above-mentioned stainless steel plate in the washed state is wiped with a sponge pad forming the stamp surface of the stamp spray, and then the sponge pad is washed with 0.1% each of Sudan # 3 and oil yellow (both oil coloring reagents). The solution was shaken and contacted with 0.2 ml of a chloroform solution, dried for 1 minute, pressed against the surface of the filter paper (adsorbent sheet), stamped, and the coloring on the filter paper was visually observed.
Table 1 shows the results.

残っていることがわかる。As is clear from Table 1, in the case of the stainless steel plate in the unwashed state and the incompletely washed state, a red color was observed on the sponge pad surface due to the contact with Sudan # 3, and the oil erosion was observed. Yellow color was observed on the surface of the sponge pad upon contact with the filter paper, and these were pressed against the filter paper surface and stamped to transfer a red or yellow color on the filter paper surface. This indicates that stains of soybean oil remain on the unwashed and incompletely washed stainless steel plates.

ず、洗浄が完全であったことがわかる。On the other hand, in the case of the completely washed stainless steel plate, no color was observed on the sponge pad surface due to the contact with Sudan # 3 and the oil yellow. Of course, even when this was pressed against the filter paper and stamped, no color was transferred to the filter paper at all. From this, it can be seen that no stain of soybean oil remained on the stainless steel plate in the completely washed state, and the washing was complete.

できる。In addition, the above-mentioned determination can be made only by wiping the stainless steel plate with the sponge pad surface, contacting the wiped sponge pad with a fat-and-color developing reagent, stamping the filter paper surface, and visually observing the color development state. It is done simply, quickly and reliably. In addition, the stamped filter paper can be stored as a record as it is, and therefore, it can be said that the determination method according to the present invention facilitates storage of the determination result.

The coating was uniformly applied in the same amount and heated and aged to obtain a stained plate. Each of the stained plates was left uncleaned in the same manner as in Example 1.
Alternatively, it was set to an incompletely washed state and further to a completely washed state.
