What happens to the boiler mechanical cleaning hours if the EDTA cleaning is successful?

When EDTA cleaning of a boiler is successful, mechanical cleaning hours are effectively zeroed out. This is because the use of EDTA, a chelating agent, is designed to remove scale and deposits from the boiler without requiring additional mechanical intervention. When the chemical cleaning is successful, it negates the need for the extensive mechanical cleaning that would typically be necessary to maintain boiler efficiency and performance. Consequently, the recorded mechanical cleaning hours would be adjusted to reflect this successful removal of buildup and thus reduced to zero. This outcome highlights the effectiveness of chemical cleaning in maintaining boiler integrity while minimizing labor hours associated with mechanical cleaning methods.
