摘要： System (200) for selectively contacting a cleaning composition (10) with a surface of a turbine engine component is presented. The system includes a cleaning apparatus (210) and a manifold assembly (220). The cleaning apparatus (210) includes an upper portion (211) and a lower portion (212) defining a cleaning chamber (213) configured to allow selective contact between the cleaning composition (10) and a surface of the first portion of the turbine engine component. The upper portion (211) includes a plurality of fill holes (201) in fluid communication with the cleaning chamber (213), and the lower portion (212) includes a plurality of drain holes (202) in fluid communication with the cleaning chamber (213). The manifold assembly (220) is configured to selectively circulate the cleaning composition (10) from a reservoir (250) to the cleaning chamber (213) via the plurality of fill holes (201), and recirculate the cleaning composition from the cleaning chamber (213) to the reservoir (250) via the plurality of drain holes (202). Methods for selectively cleaning a turbine engine component is also presented.
