The radiation (4,6.8) emerging is determined or registered for at least one wave length range with a narrow band. The result is used to determine the type and concentration of the contents of the washing or rinsing solution (13). The washing or rinsing process is optimized in the light of the data. The installation for carrying out the process features a light source (1), a transparent container for accommodating washing or rinsing solution (13), and a photoreceiver (3).
