The cleaning is performed when a boiler is filled with a water-based chemical solution. The solution is heated either by starting the boiler itself or by using steam from an external boiler. Maintaining the conditions above the boiling point, chemical concentration, and oil content are monitored for a certain period of time or until the oil content drops to a predetermined level.
