According to the fundamental cleaning model of the Sinner's circle (Sinnerscher Kreis), if the cleaning temperature (Temperatur) is reduced from 60 °C to 20 °C during a floor maintenance procedure, how can an equivalent cleaning result be achieved?

By proportionally increasing one or more of the other three factors: chemical concentration (Chemie), mechanical action (Mechanik), or contact dwell time (Zeit). By reducing the mechanical pad pressure and decreasing contact dwell time to prevent chemical dilution. By completely replacing surfactants with neutral water and doubling the scrubber-drier forward speed. By adding an inert filler to the cleaning solution to increase physical density without altering time or mechanics.

Correct Answer:

By proportionally increasing one or more of the other three factors: chemical concentration (Chemie), mechanical action (Mechanik), or contact dwell time (Zeit).
