text: Temperature of the cleaning solution. Elevating the temperature of a cleaning solution increases its dirt removal efficiency. Molecules with high kinetic energy dislodge dirt faster than the slow moving molecules of a cold solution.
  Concentration of the cleaning agent. A concentrated cleaning solution will clean a dirty surface much better than a dilute one due to the increased surface binding capacity.
  Contact time of the cleaning solution. The longer the detergent contact period, the higher the cleaning efficiency. After some time, the detergent eventually dissolves the hard stains/soil from the dirty surface.
  Pressure exerted by the cleaning solution (or turbulence). The turbulence creates an abrasive force that dislodges stubborn soil from the dirty surface.
