Rapeseed oil (manufactured by Wako pure chemical industries, Ltd.) was added at a concentration of about 1mg/cm²The coating was applied to a Test piece (SUS 304, 1 mm. times.25 mm. times.70 mm) (mass x) weighed in advance using an electronic balance 4 bits after a decimal point, and then the Test piece was weighed (mass y) using a balance 4 bits after a decimal point.

The germicidal detergent composition was sprayed in a foam form using a pump foamer (for soft hand lotion, manufactured by Kao corporation) onto each of the oil-coated test pieces, and left to stand in a horizontal state for 20 minutes. The test piece after 20 minutes of cleaning was rinsed with tap water at 25 ℃ for 1 minute using a Leanuts tester (water amount 700ml, rotation speed of rotary wing 300 rpm). After washing, the test piece was air-dried at 20 ℃/40% humidity for one day and night, and the mass of the cleaned test piece was weighed (mass z) by an electronic balance 4 after a few hours.

The cleaning rate was determined by the following equation using the masses x, y, and z. The results of the cleaning ratio of the rapeseed oil-coated state are shown in table 1. In this evaluation, the cleaning rate is preferably 75% or more, and more preferably a larger value.
