Sinner's Circle, Common Sense
In cleaning operations, the final result is influenced by four interdependent factors, grouped together in Sinner's Circle. If one of the factors is reduced, this loss must be compensated for by increasing one or more of the other factors.
1st Factor of Sinner's Circle: Chemical Action
Represents the action of an alkaline or acidic detergent solution. This action is increased or decreased by the concentration of pure product contained in the solution (water + product mixture).
It is important to respect the product dilution in cleaning operations.
Both “over-dosing” and “under-dosing” have implications for the expected result.
2nd Factor of Sinner's Circle Mechanical Action
It is the action brought about by the use of equipment (single-brush machine, scrubber-dryer) which generates friction and pressure.
In the absence of equipment, the agent is considered a mechanical action by its action of rubbing using a scraper or rubbing bar.
In cleaning operations, the mechanical action must be modulated in order to avoid alterations to the support.
3rd Factor of Sinner's Circle: Action Temperature
Thermal action is illustrated in several cases in cleaning activities.
Water temperature in product dilution: Hot water promotes the detergency of a product, and the different powers (wetting power, sequestering).
This concept is found in the case of dishwashers and washing machines where the impact of temperature has a direct influence on the result.
The thermal action is provided by the friction of a disc on a support (spray method, dry stripping).
It promotes the action of thermo-reactive products such as spray method products and dry strippers.
4th Factor of Sinner's Circle: Time Action
The notion of time or duration of contact is often found in the duration of washing cycles (in washing machines or dishwashers).
We also find it explicitly in compliance with disinfection standards where every standard is linked to a contact time.
