Methods of pressure cleaning or coating a target surface of an article comprising one or more passageways include fluidly connecting a pressure masker comprising pressurized masking fluid to a first side of at least one passageway, passing the pressurized masking fluid through the at least one passageway from the first side to a second side comprising the target surface, and, cleaning the target surface using a cleaning material (or coating the target surface using a coating material), wherein the pressurized masking fluid passing through the at least one passageway prevents the cleaning material (or coating material) from permanently altering a cross sectional area of the at least one passageway.
