The success of cleaning and disinfection depends primarily on four factors:
- Chemical (cleaning/disinfectant and its concentration)
- Mechanical (dissolving dirt, soaking dirt)
- Temperature
- (Effective) time, establishing contact with the agent usedEffective) time, establishing contact with the agent used
These factors and their mechanisms of action determine the "Sinner's circle".
All four factors are dependent on each other but can vary significantly in terms of size.
