Abstract
A cleaning method according to the present invention comprises mounting the metal filter on a jig that is vertically elevatable and horizontally slidable in a cleaning bath so that the opening is faced downward, descending the jig so that a first nozzle installed in the cleaning bath enters the opening, injecting a predetermined amount of water and a cleaning solution into the cleaning bath so that the metal filter is immersed, spraying compressed air through the first nozzle to discharge bubbles of the compressed air toward an inner surface of the metal filter, draining the cleaning bath, spraying water through a second nozzle to remove the cleaning solution from the metal filter, and spraying the compressed air through the first nozzle to dry the metal filter. An apparatus for cleaning a metal filter is also disclosed.
