Why does a cleaning agent work exceptionally well for one customer but barely at all for another? The answer almost never lies with the cleaning agent alone. Whether a cleaning process is successful depends on four factors that work together: chemistry, mechanics, temperature and time. This principle is known as Sinner\u2019s Circle. Those who understand it can specifically improve cleaning processes, and that is precisely where we can support you.<\/p>\n

What is the Sinner\u2019s Circle?<\/h2>\n

In 1959, the chemist Herbert Sinner described how every cleaning result is determined by four factors. In the circle, each factor is represented by a segment. Together, they always account for the entire cleaning result.<\/p>\n

The essence of Sinner\u2019s circle: if one factor decreases, others must increase so that the result remains the same. A few examples:<\/p>\n
