It is mainly intended to provide an indicator whereby the effects of washing and disinfection can be checked. Namely, a means for achieving the above object relating to an indicator for checking washing/disinfection which is characterized in that 1) a first layer comprising simulated contaminants and 2) a second layer comprising a composition undergoing a color change upon heating are formed on a base. More specifically speaking, the simulated contaminants contain proteins. The indicator for checking washing/disinfection as described above makes it possible to check not only washing effects but also disinfection effects. Since this indicator has a sheet shape having the layers for checking both of these effects on a base, it is also excellent in convenience, economic efficiency and so on. |
