The removal of oil-based contaminants is similar to washing of greasy dishes — with a hot water it goes much faster!
Also in 1959 Dr. Herbert Sinner, former head of tenside chemistry at Henkel in Germany formulated the basic principles of surface cleaning from pollution. The bottom line is that the most effective solution to any cleaning task depends on the right combination of all 4 factors:
- temperature
- detergent
- time
- mechanical impact
The above points can be easily represented in pie chart — this is where the name of the 'Sinner Circle' theory came from. The essence of the Sinner circle is that with a decrease in the impact of one of sectors will need to increase the impact of other sectors.
