How do you clean a nozzle in an oil burner?

Using a nozzle cleaning tool or replacing the nozzle if it is clogged is the best practice for maintaining oil burners. The nozzle plays a critical role in atomizing the oil for combustion, and any blockage or buildup can significantly impact efficiency and performance. A specific nozzle cleaning tool is designed to clean without damaging the delicate components of the nozzle, ensuring that the spray pattern remains effective for optimal combustion.

If the nozzle is too clogged to clean adequately, replacement is the most reliable option. This helps maintain consistent oil flow and ensures the burner operates as intended, preventing issues such as incomplete combustion which can lead to increased emissions and soot buildup.

The other methods listed may not adequately address the issue. Wiping the nozzle with a cloth could only remove surface dirt but wouldn't resolve internal clogging. Submerging the nozzle in water can lead to moisture getting trapped inside, potentially causing further operational issues. Running it under high-pressure air might not effectively clear blockages either and could risk damaging the nozzle. Therefore, using the correct tools and methods is crucial for optimal oil burner maintenance.
