Airman 1st Class Charles Mills, 28th Maintenance Squadron nondestructive inspection technician, immerses a hydraulic accumulator into hydrophilic remover during an inspection at Ellsworth Air Force Base, S.D., Aug. 9, 2013. The hydrophilic remover fluid removes any excess penetrant from the surface of the part to prevent false indication readings, allowing for a proper inspection and examination.
