Abstract
To improve dust removing performance and to prevent re-adhesion of dust in dust cleaner for removing dust adhering to the surface of an object such as a timepiece component by effecting blow-off dust removal and charge elimination by the use of a clean compressible fluid and an electric static ion eliminator. A clean compressible fluid is discharged from a clean compressible fluid nozzle to an object. When the object is an electro-statically charged article, an electric static ion mix clean compressible fluid containing electric static ions generated from an electric static ion eliminator is discharged to the object. It is possible to employ the structure wherein the object is set into a blow washing tray, and is moved up and down by the emission of the clean compressible fluid.
