ABSTRACT:
It is intended to provide a method whereby residual detergent (surfactant) can be conveniently and accurately detected in the step of washing or rinsing dishes or clothes, and a test device usable in examining the rinsed conditions. Namely, a method characterized by comprising bringing a test substance with a composition (test agent) comprising an oxalic acid ester, a fluorescent substance, hydrogen peroxide and a strong acid and thus easily detecting the residual detergent sticking to the surface of the test subject from the chemiluminescence thus caused; and a test device which is most suitable for storing the test agent as described above.
